Inconsistent treatment of internal pins as endpoint for "To" and "From"

[smunaut]

I want to analyze some internal path (starting or ending to internal pins). And generally that works, I get the path analyzed and reported.

However something annoying is that for Starting point a warning gets printed , for instance : Warning: signoff.sdc line 104, 'top_I.branch[28].block[15].um_I.[block_28_15.tt](http://block_28_15.tt/)_um_I/buf_out_uo_out_0/X' is not a valid start point.

Even though I repeat, it works. That end point will be in the final report and marked as internal endpoint and all is fine.

And the same warning does not get printed for internal destination endpoint, only starting one.

Looking at how they are validated to print that warning, I see that there is :

• Sdc::exceptionToInvalid() in sdc/Sdc.cc
• Sta::exceptionFromInvalid in search/Sta.cc

And the conditions in there are different and I don't really see why internal pins would be considered invalid ...
