Verilator

Unfortunately CPAN install rules don't have a way to install includes (that I'm aware of). Therefore if you need the includes for Verilator, you still need to have the kit around to point to. Sorry.

HI,i installed verilator in /tools/openrisc/verilator, but i can only see bin and share directory, but no include directory. is that right? or i had done something wrong or miss something? when i use make prepare-vlt command in orpsoc project, it reported: ../include/verilated.mk: no such file or directory

i find that there is share/verilator/include directory, so i linked it to verilator root directoy, then re-run it. the error message above gone, but a new error come. No rule to make target verilator_bin: needed by Vorpsoc_top_ver.d

i have add verilator install directory to PATH, i have tried to set and unset VERILATOR_ROOT variable, the result are the same. what else i can do to move this forward?

thanks !

Verilator installs the includes by default in share as you noticed. It then remembers that path for the makefiles it builds. If you try the example in the verilator manual, I suspect it will work, if not post here. Otherwise I don't know what prepare-vlt does, it looks like it isn't using the proper generated makefile, or maybe it needs some other special setup, you'll have to contact the author of the prepare-vlt script. Sorry.

hi, Wilson, thank you for your kindly reply.

i un-tar verilator at folder ~/verilator-3.820, and installed verilator at /tools/openrisc/verilator directory,and there are bin and share folders. in the verilator-3.820/test_c directory, i type: make then the test goes all right. in verilator/share/verilator/example/test_c directory, when i type: make there are errors reporting: ../include/verilated.mk no such file or directory. i find that it is the relative directory path not correct.

so, you mentioned try the example in the verilator manual, is this test be proper for the problem diagnoze.

maybe i should not specify the install path rather than use the default configuration?

the prepare-vlt script is from the openrisc project from opencores.org.

Ah, I see. "make test" is only intended to test the kit in place, between compiling verilator and installation, not after installation. The example in the manual is for after installation. If the example in the manual works, which I suspect it does, and prepare-vlt doesn't then the openrisc people are who to contact - I'll help them if they want, but don't have control over that source.
