Thanks for the info Jim! I was dealing with some unusual sizes for logic vectors. So, I just resized them in my VC to have a bigger width to capture all of the data since I actually wanted to capture all of the data bits, not just some of them. I now don’t get this error anymore.

Hi, I’m working with a test bench that I made in OSVVM. I have a transaction with a proprietary protocol we use at my company. I’m trying to check data when a control signal goes high, but this Default keeps throwing away transactions even though the waveforms look correct. In my testcase, everything passes. It’s in Default, which I’m not entirely…[Read more]

This is resolved now. The problem was I was calling the VC directly instead of WRITE or READ, which calls the operations in my VC.

Hi I’m having an issue trying to make a testcase for a proprietary protocol. I’m using Questa Sim. When compiling the testcase file, I get these errors: # ** Error: ../testcases/file.vhd(92): (vcom-1348) Prefix (enumeration literal “WRITE_OP”) of indexed name is not an array.
# ** Error: ../testcases/file.vhd(94): (vcom-1348) Prefix (enumeration…[Read more]

Hi Jim,

Thanks for the speedy reply. I can’t post the DO file, but I can try to post the what it is supposed to do. This test bench passes vector files which poke around registers. The vector files use a custom API that my team developed that go through a VHDL file to a VHDL test bench. It is based on OSVVM, but there’s the extra layer from our…[Read more]

I have a test bench that is run from a DO file. It is based on OSVVM. We were wanting to add code coverage, so I was looking into making a PRO file with the settings SetCoverageAnalyzeEnable and SetCoverageSimulateOptions set to true. But I’m not sure how to run the DO file in that PRO file. I’m relatively new to OSVVM, so any input is…[Read more]
