08:12 PM Issue #1264: verilator generates bad C++ with --public for module binds
The testcase is too large for me to compile on my machine, can you please create a small example, thanks.
Wilson Snyder
08:06 PM Issue #1260 (Resolved): verilator runs out of memory at gateAll
The code has thousands of lines similar to this
assign FOO_1 = (BAR == 13'h101) ? 64'h0 : FOO_0;
assign FOO...

03:32 AM Issue #1267 (Resolved): Unlinked error on input-only tristate comparisons
Fixed in git towards 3.919. I also tested all other models in the library.
However, basically the tristate compar...

Todd, thanks for that.
Indeed, it doesn't work out of the box. I need to make some changes in the lpm_mult.v but I k...

Todd, thanks for the pointer.
Alexis, as to this specific error, if you can provide a small completely standalone ...

01:21 PM Issue #1267: Unlinked error on input-only tristate comparisons
The Altera libraries have some seemingly meaningless Verilog nastiness in them. We put these scripts together to get... Todd Strader
04:48 AM Issue #1267 (Closed): Unlinked error on input-only tristate comparisons
I am using basic Altera's IPcores such as *220model.v* (for `lpm_mult`) and *altera_mf.v* (for `scfifo`).
Code sni...

01:27 AM Issue #1264: verilator generates bad C++ with --public for module binds
The testcase is the same as in #1260 but with -Og -Wno-fatal --public Alex Solomatnikov
01:24 AM Issue #1260: verilator runs out of memory at gateAll
BTW, the same testcase compiles with -Og -Wno-fatal, then clang++ compiles C++ Alex Solomatnikov

11:44 PM Issue #1260: verilator runs out of memory at gateAll
The testcase is ready but it is large: ~.5.5 MB in compressed form. What's the best way to send it? Alex Solomatnikov
05:53 PM Issue #1266 (NoFixNeeded): Issue with behavioural SRAM model bigger than 64-bit
Use --unroll-count 256
Note this is why it says to see the documentation ;)

02:26 AM Issue #1265 (Resolved): Fix status code of generated Makefile
Thanks for the patch. I added removing it from the test_regress makefile too.
Fixed in git towards 3.920.

06:33 PM Issue #1265: Fix status code of generated Makefile
I also think that all recent linkers do the demangling themselves pretty well. For the sake of simplicity I also thin... Stefan Wallentowitz
12:50 PM Issue #1265 (Confirmed): Fix status code of generated Makefile
I can't find a definitive reference, but believe c++filt isn't required for any modern linker, so could be removed. D... Wilson Snyder

01:02 AM Issue #1262 (AskedReporter): Query parameters in simulation run
In general I'd avoid public as it isn't simulator portable. The ideal performance-wise is perhaps to have verilog in... Wilson Snyder
10:08 AM Issue #1265 (Closed): Fix status code of generated Makefile
Hi Wilson,
we use verilator in a larger build process that is driven by a script. It aborts on any error, but the ...

12:56 AM Issue #1261 (Resolved): verilator generates bad C++ with --public for real module parameters
This is fixed in git towards 3.920, but simply by not putting out real parameters.
Wilson Snyder
12:33 AM Issue #1264 (AskedReporter): verilator generates bad C++ with --public for module binds
Can you please provide a standalone test case in "test_regress" format?
Wilson Snyder
12:31 AM Issue #1260 (AskedReporter): verilator runs out of memory at gateAll
Believable, but will need a testcase (or ideally your own debugging) to figure out why it's so bad.
