Description

Sorry, I don't know how to re-open a closed issue.. (can I even do that?)

A year ago I reported issue #823: Incorrect results with partially out-of-bounds part select:
http://www.veripool.org/issues/823-Verilator-Incorrect-results-with-partially-out-of-bounds-part-select

This ticked has been closed as "Fixed in git towards 3.865".

However, with current git head of verilator (commit 373a68e) I can still reproduce the problem, using exactly the test case that I posted in issue 823:

History

#1 Updated by Wilson Snyder about 3 years ago

Sorry, the test case I extracted and fixed had the opposite bit ordering. I've started on a patch, but it makes a mess of other tests, so more work is needed. Stay tuned.
