* Replace DelayInfo with DelayPair/DelayQuadgatecat2021-02-191-14/+12
| | | | | | | | | | | | | | | | | 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.

* Mark IdString and IdStringList single argument constructors explicit.Keith Rothman2021-02-041-3/+3
| | | | | | | | | Single argument constructors will silently convert to that type. This is typically not the right thing to do. For example, the nexus and ice40 arch_pybindings.h files were incorrectly parsing bel name strings, etc. Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

* nexus: Switch from RelPtr to RelSliceD. Shah2021-01-271-37/+31
| | | | | | | | | | This replaces RelPtrs and a separate length field with a Rust-style slice containing both a pointer and a length; with bounds checking always enforced. Thus iterating over these structures is both cleaner and safer. Signed-off-by: D. Shah <dave@ds0.me>
