Hi,
I'm currently trying to simulate the Hard memory controller example, and the files in "vhdl/submodules" are very long. For some reason modelsim fails to read any of the files with filenames greater than 83 characters !?? I'm running Quartus/modelsim under Windows XP 64 bit, a work colleague has Windows 7 64 bit, and modelsim has no problems reading the same files ! Any help would be much appreciated Thanks LeeLink Copied

--- Quote Start --- put your project into a subfolder directly over a HDD for example D:\ms\ --- Quote End --- Hi, just tried that, still the same. Lee

If I shorten "ddr_uniphy_hc_example_sim_e0_if0_c0_csr_translator _avalon_universal_slave_0_agent_rdata_fifo.vho" to "ddr_uniphy_hc_example_sim_e0_if0_c0_csr_translator _avalon_universal_slave_0_agent_r.vho" (83 characters) it finds it !

Windows XP has a limit on the total pathname length of 250 chars, not on the filename length. The pathname includes the starting "C:\" and null and the end of the path.

Thanks, made interesting reading, same problem I had, I also can't believe the filenames have to be so long either !

Yep, not only did they leave their brains at home on the day that they created those long filenames but there was an astonishing lack of testing.
