06:25 AM Usage: RE: Trouble simulating altera-generated floating point units: It's a fundamental problem, try rewriting. Wilson Snyder
02:31 AM Usage: RE: Trouble simulating altera-generated floating point units: Is this problem fundamentally due to verilator being a cycle simulator instead of an event simulator? Will it be poss... Evan Andersen

07:32 PM Usage: RE: Trouble simulating altera-generated floating point units: Hmm, I don't think it's related to that. I just used 'x' as a variable name in my previous code example. There is alr... Evan Andersen
01:40 PM Usage: RE: Trouble simulating altera-generated floating point units: You could try the --x-initial-edge flag. Or, add an initial statement. Wilson Snyder
08:35 AM Usage: RE: Trouble simulating altera-generated floating point units: Ok, I have figured out the issue, but I am unsure how to solve it. Inside the altera memory sim libraries, there is c... Evan Andersen

01:29 AM Usage: RE: Any chance to use Verilator together with Icuras?: Great! There's been a lot of progress in the last month or so, with --protect-lib added etc, please see bug1572. I'... Wilson Snyder
12:44 AM Usage: RE: Any chance to use Verilator together with Icuras?: ... "Verilator has plans to add "embedding" of a model in another simulator"
This is exactly how I use Verilator w... Julien Margetts

11:21 AM Usage: RE: Trouble simulating altera-generated floating point units: Glad you're giving Verilator a try. It's most likely something simple, perhaps with a hint buried in a warning as yo... Wilson Snyder
07:00 AM Usage: Trouble simulating altera-generated floating point units: It is my first time using verilator. I wrote a simple program to test the floating point units generated by altera's ... Evan Andersen

03:06 AM Usage: RE: Basic questions: Multiple modules and using "#": 1) Yes, you can put multiple modules per file.
2) You'd write this in C code, for example in = 0; then make time p... Wilson Snyder

09:01 PM Usage: Basic questions: Multiple modules and using "#": Hello,
I want to play with some simple modules and signals and tried this:... Patrick Mulder

09:52 AM Usage: RE: Very basic eval() usage question: No idea, obviously makes no sense at first glance; try stepping through in the debugger. Let us know what it turns o... Wilson Snyder
03:31 AM Usage: Very basic eval() usage question: I want to write some functions in the same C++ file as the main() function is in which will also call top->eval();
... Julius Baxter

11:58 AM Usage: RE: Testbench patterns to run N cycles ?: It finishes when there's a $finish, that's not really a signal.
Anyhow the example you point to should have s $fin... Wilson Snyder
11:50 AM Usage: Testbench patterns to run N cycles ?: Hello,
as I understand from the example sim_main.cc replaces the testbench.
The main loop stops when it receives ... Patrick Mulder
10:00 AM Installation: RE: Windows MinGW/Msys based build: Thanks, yes that works:
pacman -S mingw-w64-x86_64-verilator
Also, thanks for the additional pointers. Patrick Mulder
12:11 AM Installation: RE: Windows MinGW/Msys based build: As I said before, you shouldn't put /usr/include on the path, it will break everything. The easy thing to do is just ... Patrick Stewart

09:08 PM Installation: RE: Windows MinGW/Msys based build: In config.log there is already this:... Patrick Mulder
09:03 PM Installation: RE: Windows MinGW/Msys based build: I tried:

11:26 AM Development: RE: Anywhere to find the description of cycle based simulator: Verilator figures out the logic graph of the code, basically as a cone, and starts from inputs evaluating what that n... Wilson Snyder
06:49 AM Development: RE: Anywhere to find the description of cycle based simulator: Or simply evaluate twice without advance the time? Yong Fu
05:48 AM Development: RE: Anywhere to find the description of cycle based simulator: Thanks Wilson.
The general understand of the CBS algorithm is:
1. simulate all combinational elements;
2. s... Yong Fu
