Hello,
I have an old R2011b Simulink model that I tried opening in R2025b. Upon opening the model in R2025b, I see the following:
My "CAN Setup" block in Simulink is highlighted in red and says: "xpclib" not found. The top yellow banner says: "This model contains Simulink Real-Time features that are incompatible with the current release. Open Upgrade Advisor and select "Check model for upgradable Simulink Real-Time features". Upon running the Upgrade Advisor, I get the following error:
Error occurred during model compile.
Failed to load library ‘xpclib’ referenced by ‘CAN Setup’.
Any idea on how to solve this particular problem? My understanding is that ‘xpclib’ (xPC Target) no longer exists in R2025b because it was replaced by Simulink Real-Time. I just don’t know how to convert my block to the newer library.
Thank you!Hello,
