DSIM UVM Hello World Project giving error

Hello

While elobrating the UVM hello World project I am getting following error on windows machine. I have a feeling it has to do with some eniroment setup where space in the environment setup is not being handled.

 The following dynamic $cast cases will always be false

Altair DSim 2025.0.1 is now available in the AltairOne Marketplace. This release should fix the issue.

Shaun_Altair

This issue is a known limitation for Windows machines and will be fixed in the next release of DSim.
Limitation: DSim cannot find UVM library on Windows machines
