Remove unused advanced timing constraint API
|
|/

|
|
|
|

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.

-Werror is not enabled by default, except on CI and for a few specific common traps, to avoid the inevitable breakages when new compiler versions add new diagnostics.

Add constant network support to FPGA interchange arch
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
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.

Create an empty temporary file for stdin; so reads fail rather than
locking up (otherwise doing help() would be enough to completely lock up
the GUI).

This replaces the arch-specific DelayInfo structure with new DelayPair
(min/max only) and DelayQuad (min/max for both rise and fall) structures
that form part of common code.
This further reduces the amount of arch-specific code; and also provides
useful data structures for timing analysis which will need to delay
with pairs/quads of delays as it is improved.
While there may be a small performance cost to arches that didn't
separate the rise/fall cases (arches that aren't currently separating
the min/max cases just need to be fixed...) in DelayInfo, my expectation
is that inlining will mean this doesn't make much difference.
