Using Unit Delays in triggered Subsystems for HDL Codegeneration

2 views (last 30 days)
i'm having some Unit Delays in a Triggered Subsystem. When generating VHDL Code using Mathworks HDL Coder I get the following error:
Error: Cannot find valid sample time for clock request from block. Please ensure that the block has a valid discrete sample time.
The only valid value for the sampletime is '-1', which i have set. This error occurs in R2017b, in R2015b it is working.
How can i get this working again?
Best Regards, Alexander Kiermayer

I solved the problem. I had a Limited Counter for triggering the subsystem. After replacing it by an HDL counter, everything is fine

This should work fine, and does in a small test I just tried. Can you open a customer support case so that this may be further investigated?
