How do I pass a string from irun to my DPI-C codes?

Ncsim User 1 over 6 years ago

I use DPI-C to compile a C code and run with irun.

Assume I wish to pass a testcase directory to my C and Verilog codes. I managed to do it for Verilog but not my C code.

#!/bin/ksh

#TC=$2
TC=TEST_1

irun -64bit -access +rwC -g \
-gui \
other flags \
-DMYTC="TEST_1" \
other flags

IN my C code I would use
sprintf(str_filename, "%s/my_testcase.txt", MYTC);

You can use "irun -defineall MYTC=TEST_1" to pass the same define to all language compilers. Alternatively you can pass strings from SV to C on the DPI call...
