ah.  that tells me that you may be on the wrong branch (or git repo)

there's three functions that do routing, and they are all separate functions:

* add()   - which uses add.vst to create add.ap
* sub()   - which uses sub.vst to create sub.ap
* alu16() - which uses alu16.vst *and* add.ap/vst *and* sub.ap/vst to create
            alu16.ap

that seems likely.  did you check the git versions i sent a couple of messages
back?

for alliance you should have this in .git/config:
[remote "origin"]
        url = https://gitlab.lip6.fr/vlsi-eda/alliance.git

where git branch should be "master"


and for coriolis2:

[remote "origin"]
        url = https://gitlab.lip6.fr/vlsi-eda/coriolis.git
...
...
[branch "devel"]
        remote = origin
        merge = refs/heads/devel

where git branch should be "devel".


and alliance-check-toolkit:

[remote "origin"]
        url = https://gitlab.lip6.fr/vlsi-eda/alliance-check-toolkit.git

where branch should be "master".


you should be on:
