Accessing C code generated from veriloga compile

RobinCommander

Is it possible to access the C code generated by the veriloga compiler?

With the ahdlcom option on I get "ERROR (VACOMP-1008): Cannot compile ahdlcmi module library. ..." problems. The log files tell me the problem C code files & lines but then deletes these files so I don't have any clue as to where it is going wrong.

Running with ahdlcom 0 gets round the problem

 

While I am here I found a couple of possible minor bugs with the veriloga {} string concenation operator.

$display("test 0x %s",{0{"ab"}});  // <- should be null string?
$display("test 1x %s",{1{"ab"}});
$display("test 2x %s",{2{"ab"}});
teststr = "abcdef";  //teststr is string type
$display("test append %s",{teststr.substr(0,2),"xyz"});

Produces:

test 0x ab
test 1x ab
test 2x abab
test append abc

I tried {0{"ab"}} in Hspice to get a second opinion but it refused to run.

  • Robin,

    For the first issue, you shouldn't really need to look at the C code - if the C code is causing a complication failure, that's a bug, and so you should report it to customer support with a testcase that we can reproduce it and get it fixed.

    For the other two minor bugs, I created cases and CCRs on your behalf. For the second one, you can workaround it by doing:

    otherstr=teststr.substr(0,2);
    $display("other append %s",{otherstr,"xyz"}); // correctly outputs "abcxyz"

    Regards,

    Andrew.
