How do you merge coverage in VCS?
I tried this command,
urg -dir <my_compile_model.simv.vdb> -dir <test1_path/result.simv.vdb> -dir <test2_path/result.simv.vdb> -dbname MERGE_COV
But I'm having an error saying that the testname is invalid. Below is the exact error,
Error-[UCAPI-ITN] Invalid...
I'm running a simulation in Synopsys DVE. This simulation runs for almost a whole day... As I was running, the simulation crashed! So I open the waveform again but I don't want to restart the simulation from the start. What I want is to resume the simulation from the current time it crashes. Is...
Let's say these are bidirectional ports. In netlist the connection is,
IO1 <-> IO2_a <-> IO3_a
IO2_a <-> IO3_b
Note: IO2_a branched out to IO3_a and IO3_b.
But in the SDF,
INTERCONNECT IO3_a IO3_b (....)
INTERCONNECT IO3_b IO3_a (....)
Note: IO3_a and IO3_b are driving each other according to...
Oh yeah. It should be in between.. Then if I run the simulation without specifying maximum and minimum, it will run in typical, right? Then what value will the simulation use?
Let's say I have this value in low to high of an INTERCONNECT delay, (1::3). Notice that only the maximum and minimum has a value but the typical is missing. In this case, what is the value for the typical? Is it 0?
1.) What is a black box in a netlist?
2.) Why do we have it? Is it to hide the IP?
3.) If you are looking in a netlist, how can you identify that a module is a black box?
4.) If it is a black box, does its module definition needs to be present to compile the netlist?
5.) If you are going to...
Hi KlauST,
So this means that the reason why we use PLL is because the input frequency is fixed which limits the application to that certain frequency only. Thus, with the use of PLL, we can derive different frequencies based from the input frequency. Is this correct?
Then the registers are...
In most ICs I encounter, PLLs are present. But I don't know actually what's the use of it. Some registers are associated with it which you need to program. May I know what's the use of this PLL and why are the registers need to be configured?
I know how PLL works. It takes 2 input frequencies...
That's great! :) I'll try that and also the free student version of Model sim.
I'm also looking into buying an FPGA. I'm not sure if they will provide a library that accurately models the gates of their FPGA..
I'm lacking experience in Gate Level Simulation so I want to practice more or gain more experience on solving issues on this level. The problem is, I want to do this at home, not in my office, so I need a software tool that can run GLS. Cadence and Synopsys need a license and that is very...
But mail.id is for humans to make it easy for us to address the message to someone.. Machines do not understand this. They can only understand digits (or binary to be more specific). Routers use these digits to find their way to their destination without getting lost on so many paths on the...
Hi. Thanks for the reply. I'm not aware of this IP address spoofing.. That looks cool! :) It masks the IP address of the sender so that they cannot be traced.
But I'm just curious. If the source IP address is altered, how is it possible for the recipient to reply back to the sender, and the...
I'm trying to track the location of the person by looking at the IP address from his email. So I test the IP tracking method I read from Google and I test it to my friend's email to see if it really points to the correct location. However it turns out that the IP tracking is not really working...
