LibraryUnit adding scripts to simulate

[Li]

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 actions to be done when running
on a particular simulator.
When simulate (or RunTest) is called, it will source the following files in order, if they exist:

<ToolVendor>.tcl
<ToolName>.tcl
wave.do
<LibraryUnit>.tcl
<LibraryUnit>_<ToolName>.tcl
<TestCaseName>.tcl
<TestCaseName>_<ToolName>.tcl

ToolVendor is either {Aldec, Siemens, Cadence, Synopsys}.
ToolName is one of {QuestaSim, ModelSim, RivieraPRO, ActiveHDL, VCS, Xcelium}.
LibraryUnit is the name specified to simulate.
TestCaseName is the name specified to TestCase.

I don’t quite understand what is LibraryUnit name here. I’d appreciate it if someone can explain it more to me. Thanks!

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,

A design unit is
either an entity declaration, an architecture body, a configuration declaration, a package declaration, a
package body, a package instantiation declaration, a context declaration, or a PSL verification unit. (13.1)

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, package name and so on. They don’t work.

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? I have tried the “CODE” button, but it still does not work.
