Linting error: backward indexing

I think I met a false error in linting:
Slice selection '[2:2]' has backward indexing versus data type's '[0:3]'
Slice selection '[3:3]' has backward indexing versus data type's '[0:3]'

If the data type is declared as [3:0], then it won't complain. Therefore, it looks like that the tool treats [i:i] as big-to-small. However, it can still be treated as small-to-big.

Thanks,
Hao

Thanks for the report, simple enough to fix.

Fixed in git towards 4.420.

Thanks for the quick fix. May I know when I can start to use the new version?

You can get it now from git, see the Install section. Typically releases (tarballs) are every month or so.

Can you please see if my command has some issues? I used:

git clone http://git.veripool.org/git/verilator

Then "git tag" shows the latest version is verilator_4_018 or v4.018. Not quite sure if I missed anything.

Thanks,
Hao

It's not released (until next monthish), use master branch, that is don't use any tag.

Let me know if it is better to open a new issue, since it is unrelated topic.

I am on the master branch right now, but I don't see the updates. Please see my command history:

hao@haos:~/Downloads/test/verilator$ git branch

• master

stable

hao@haos:~/Downloads/test/verilator$ git pull

Already up-to-date.

Sorry, not having it in master was my fault, try again.
