Original Redmine Issue: 615 from https://www.veripool.org
Original Date: 2013-02-08


@t_vpi_var@ gets a mismatch (@rfr[39:0]=0x60064B1CDB@ versus @sig[39:0]=0x00064B1CDB@ in @arr[40]@). I don't know enough about VPI to see where that is going wrong.

%Error: t/t_vpi_var.v:109: Verilog $stop
%Warning: vlt/t_vpi_var: Exec of obj_dir/t_vpi_var/Vt_vpi_var failed

This was on git master branch, commit bcadb0b.

I don't see this. Perhaps there is something initialized in the test that makes it a system specific failure? I had one other similar issue which I had fixed just prior to release, there was an uninitialized variable.

Perhaps post the --verbose output and maybe Rich Porter can help as he was recently there for #�.

Is it a 32 bit build?

I've reproduced an issue with a 32 bit build - not exactly the same as above but similar.

Wilson did you try 64 or 32 bit build?

I'll fix up the issue I see.

Some long long confusion using sprintf/sscanf for the decimal string values.

I've tested this patch on 32 & 64 bit builds.

This code should be using the types as defined in verilatedos.h, i.e. vluint64_t.
