Luxembourg's Minister of Finance Pierre Gramegna told RTL that it was yet too early the gauge the true extent of the economic impact of the coronavirus crisis as the government is yet to devise a concrete exit strategy.

He confirmed that the initial state budget is recalculated due to the unexpected coronaviurs-related expenses. It was initially presumed to grow by 2. If this grim economic forecast comes true, it would be synonymous with the worst national economic result in a a very long time, the minister warned.

Gramegna negotiated in the negotiations of a European coronavirus rescue plan until Thursday evening. The staggering amount will be used to cover loans, guarantees, and short-time working schemes. Despite the grim outlook, the minister highlighted that the international sense of solidarity continued to reign strong in the European Union. The breakthrough in negotiations came after the Netherlands softened its position on the crucial question of making needy countries commit to economic reform and outside oversight in return for assistance.

The Hague had blocked the talks two days earlier by insisting that Italy, or any other country in need, deliver on governance targets -- which Rome saw as a shocking demand during a health crisis. The ministers, however, set to one side a proposal from Italy, Spain, and France for a joint borrowing instrument, sometimes dubbed a "coronabond", that would have raised money towards a recovery after the outbreak. Germany, the EU's most powerful member, has refused the pooled debt proposal and ministers agreed only to "explore" the idea under the direction of EU leaders, who are set to meet later in the month.

Data indicate that the economy across the continent is already in a historic meltdown, with everyday life paralysed to fight the spread of the virus. Despite 19 EU countries sharing a common currency, member states have reacted unilaterally to save their economies, giving richer countries such as Germany a big advantage over those with less spending power.

Italy and Spain had the backing of the majority of member states to keep the conditions for tapping the ESM to an absolute minimum, but the Netherlands fought hard for something tougher. Putting conditions on support is seen as a humiliation in Rome and Madrid, evoking bad memories of the eurozone debt crisis when auditors from Brussels dictated policy to bailed out Greece, Portugal and Ireland. Dutch Finance Minister Wopke Hoekstra insisted if a country asked for any non-virus related support from the ESM -- it would still come with conditions.

French Finance Minister Bruno Le Maire said the debate was still open and that everyone agreed that new sources of funding were necessary to restart the economy. But, repeating her well-known position, German Chancellor Angela Merkel had earlier on Thursday firmly rejected the notion of pooled debt in Europe. Sport Local International.I was interviewing with one company in Austin, TX and I was asked to design a circuit which would generate the Fibonacci Series. By definition, the Fibonacci Series of numbers are 0, 1, 1, 2, 3, 5, 8, 13, etc.

Below is the block level diagram which contains two registers to hold the current number and the next number in the sequence. There is also control logic for the enable signal which when asserted, the output of the two flops are added together and then the result is stored in the next number register on that same cycle the next number register shifts into the current number register.

When the enable signal is low, the registers hold their previous value. The book contains 41 figures and drawings, and 28 pratical Verilog code examples. A simple and common interview question for digital designers is to write Verilog code to generate Gray Code. The first method is converting the binary counter to Gray Code using a case statement. However, there is an easier method, a more general use method that you should be aware of also. The problem with this approach is that for a Nbit counter you need to explicitly decode each state.

The book contains 41figures and drawings, and 28 pratical Verilog code examples. It is a very basic question to ask for the truth table for all of the common digital logic gates nandnorandorinverter since this should be fundamentally understood. However, I have also been asked to draw the cmos level transistor equivalent. If you have been out of college for awhile, then it is important to brush up on the circuits. The below truth table and Kmap shows you again how these gates were chosen.

As usual, we always start the design process by creating a truth table, showing all possible input combinations and writing down the expected output states. Home Buy Now! Tuesday, May 19, Write Verilog code to design a digital circuit that generates the Fibonacci series. Since the circuit itself must self generate the next number in the sequence, the design must be able to hold the first two starting numbers in the sequence using 2 registers, and they should be reset respectively to 0 and 1.

Saturday, May 16, Draw digital logic gates, truth tables, and equivalent transistor level circuits.The material was recorded in the Fall of The original length of the interview was 45 minutes, but the published material is only 9-minutes long.

The part that we love the most is the first few seconds of the interview, which capture the general mood of the conversation. Yes, I am so happy that today I can get you to know such a musician. In English Welcome to the show, LP! LP: I do. Feels right. It came upon me in such a weird way. My mom passed away when I was a teenager, and she was a singer, an opera singer, and I was really into singing, and songwriting was just like a mystery to me.

LP: This was like one of those things that seem so mysterious. LP: I studied voice. I started studying voice. Just because I wanted to… My mother was… I think she saw from an early age that I was very loud.

I just needed to know how to control my voice. LP: I studied opera for a couple of years, and it was more about, it really all came down to scales. We sang some arias and stuff like that, but it was more about doing scales, and I wanted studying with other rock teachers, really. They never told me how to sing, they just kept giving me very cool scales and I did them like a guitar player, basically.

LP: I just did it, so I could. My first band, where I was felt like I was screaming a lot. Not screaming, but really wailing up rock-wise. LP: I think you can change it. I call it like a channel on. Do you play guitar at all? I feel like that is something I do vocally. And because I do a lot of writing for other people I sometimes can get in that mode, but I figured out that song can be saved. Then they told me that it was gonna meet you and you got to be here, I was like ok, I have to watch it, and I was so amazed.

LP: Oh, thanks. LMR: Yeah. LP: I think we all have that, you know what I mean? Even the most sugary perfect little button of… whatever [laughs]… of pop, is… They have to do ALL. And I hope that myself and a bunch of other people can give people hope. LMR: Do you think that the Internet and other technique stuff and all the possibilities are making it harder or easier for artists to…?

That brings us back to what we were just talking about — people can get through more unscathed and more true to themselves when they can do it themselves and just throw it on Youtube.

LMR: Always the same. LMR: Well. We could do that, I can say goodbye to people! LMR: I whistle… When I whistle on my record it sounds like shit, we need to put a lot of effects on it…. LP: You know what happens?Q3 A - D flop is data flop, input will sample and appear at output after clock to q time.

T flop is toggle flop, input will be inverted at output. Q94 Slack is margin for the timing path, it could be negative or positive. Q91 Synchronizers are to sync data from clock domain 1 to clock domain 2,sync cell prevent metastability when signal from clock domain 1 is sampled in clock domain 2. Blocking statement - evaluation and execution done before executing next statement Non-Blocking statement - Evaluation done first for all statement in always block and then execution happens. Q4 setup time - time where data should be stable before active edge of clock.

Q60 Meta-stability is state where flop output is unknownit may be 0 or. Flop will be in metastable state when any timing requirement is violated and in that window any glitch or noise can change the state of flop. Metastability means state between 1 and 0. Ans In a block, blocking statements are executed sequentially while non blocking statements are executed concurrently.

Vice Versa in the Negative skew case. This is called as Write Write race condition. We cant make sure that which one is going come as output.

Tutorials fullchipdesign.Xavier Bettel looked back at in an interview with Caroline Mart, covering topics from data protection to climate change in a year which was not always easy.

Asked whether he is relieved to see the back ofBettel admitted that the year had not been an easy one. Felix Braz's heart attack had come a year after the government lost one of its members, the Green's Camille Gira, who collapsed in the Chamber of Deputies.

He described waiting to hear information on Braz's condition as one of his worst moments of the year, and said it was a wonder that Braz is now recovering well. Despite the shuffle in government positions, Bettel does not expect many changes to take place with his new deputy prime ministers, as the coalition agreement will still take precedence.

One thing which is unlikely to change is the constitution. Bettel expressed his disappointment that the antiquated constitution could only be reformed point by point without a public vote. On the topic of referendums, the Prime Minister did acknowledge the previous referendum of was not sufficiently prepared.

One topic which the opposition enforced in the last year was climate change. The budget speech drew strong criticism from opposing MPs, who said it did not contain enough information on climate policies. However, Bettel told RTL the government had ambitious goals for environmental improvements, particularly in light of predictions for the world's condition in 20 or 30 years. He described society as being in a state of auto-destruction and said it was time to apply the handbrake and that the government would now put into motion a number of policies designed to improve the state of matters in Luxembourg.
