Bug ID: 449
Summary: FU unit tests checking output one cycle too late
Product: Libre-SOC's first SoC
Version: unspecified
Hardware: PC
OS: Linux
Status: CONFIRMED
Severity: normal
Priority: ---
Component: Source Code
Assignee: lkcl at lkcl.net
Reporter: programmerjake at gmail.com
CC: libre-soc-bugs at lists.libre-soc.org
NLnet milestone: ---
I finally figured out why the div pipe was failing with the FSM:
the unit test was checking the output one cycle later than it should. Once I
fixed that, the tests pass for all three div pipe implementations.
The unit tests for the other FUs are probably broken in the same way, so I'm
creating this bug report to track fixing it.
