Indeed, it is a process that calls a foreign subprogram. I get:
run process .tb(behav).P0 [0833A428]
../tb:error: invalid memory access (dangling accesses or stack size too small)
../tb:error: simulation failed
Here's the gist:
architecture behav of tb is
function init return natural is
begin
assert false severity failure;
return 0;
end function init;
attribute foreign of init : function is "VHPIDIRECT init";
begin
process
variable status : natural;
begin
status = init;
....
assert false report "Simulated halted." severity failure;
end process;
end architecture behav;
Obviously I have more than this, but this is pretty much what is
happening right off. So I run the testbench in gdb, and set a
breakpoint in my foreign subprogram "init". It never gets there.
So I'm thinking that perhaps a shared library is failing to load (I am
linking against the pthread library)? I can see the source code of
the "init" function, and can set breakpoints. But since it never gets
there....
Any tips?
Thanks,
Pete
