Hi Adam,
I have added some beta features to the 2023.04 release to see if we can address this better. As a Beta feature, there is no documentation yet – as it may change. See AxiStream/TestCases/TbStream_SendGetRandom1.vhd.Best Regards,

Brad Adam started the topic Creating Asynchronous Clocks in the forum OSVVM 2 years, 2 months ago
I’m looking to create a simulation that uses two asynchronous clocks, is there a way within OSVVM to add a delay before starting a clock so that it does not begin generating at time 0 in a simulation?
I’m not seeing any options for this within the CreateClock procedure, is there possibly another function that allows this behavior?
Thanks.

I just want to post my test_harness.pro and testbench.pro files here so you may understand me more clearly. But every time I post the code, it is rejected. How can I post a code segment here?

Hi Jim,
thanks for the explanation. If I make the .tcl script the TestCaseName, it will be sourced and the RAM is successfully initialized during the simulation. But I think it is sourced as <TestCaseName>.tcl but not <LibraryUnit>.tcl. Because with any other name it will not be sourced, at least in my project. I have tried testbench name,…[Read more]

LibraryUnit in this case is the name which you used with simulate, hence, either the name of your testbench or configuration that runs your testbench. Often, I try to make this the same as the TextCaseName, but it does not have to be.
In VHDL, LibraryUnit is an analyzed Design Unit and from the LRM,

Hi OSVVM fans,
I am new to this method and have just created my first project. I need to use a .tcl file to initialize a RAM. The following description I have found:
Adding Scripts to Simulate
Often with simulations, we want to add a custom waveform file.
This may be for all designs or just one particular design.
We may also need specific…[Read more] -
