HDL-Coder Delay Balancing in Feedback-Loop workaround
14 views (last 30 days)
I am trying to generate HDL-Code from a Subsystem that looks like this:
Inside Subsystem 2 and 3 there is some combinatorial logic with multipliers, adders etc. that need Delay-Balancing and Pipelining to achieve the desired Clock-Frequency.
Unfortunately hdlcoder refuses to perform delay-balancing and pipelining. It tells me:
"Delay balancing unsuccessful because Delay introduced in feedback loop cannot be path balanced"
"Unable to insert required number of pipeline registers because the Block is in a feedback path"
Is there a way to perform these optimizations in Subsystem 2 and 3 as if there was no Feedback-Loop involved?
