|\ | | | | Remove unused advanced timing constraint API
| * Remove unused advanced timing constraint APIgatecat2021-02-262-187/+0
|/ | | | | | | | | | | | | This API was simply an attractive nuisance as no code was ever developed to actually process timing constraints (other than clock constraints which use a different API). While I do want to consider basic false path support, among other things, in the near future; I plan for this to use a new API that doesn't add complexity to the BaseCtx/Context monstrosity and that is easier to use on the timing analysis side.

| | | | | | | | | | | | | | | | | | | | Fixes: - Only use map constant pins during routing, and not during placement. - Unmapped cell ports have no BEL pins. - Fix SiteRouter congestion not taking into account initial expansion. - Fix psuedo-site pip output.
