* Split nextpnr.h to allow for linear inclusion.Keith Rothman2021-03-153-10/+21
| | | | | | | | | | | | | | | | | | | "nextpnr.h" is no longer the god header. Important improvements: - Functions in log.h can be used without including BaseCtx/Arch/Context. This means that log_X functions can be called without included "nextpnr.h" - NPNR_ASSERT can be used without including "nextpnr.h" by including "nextpnr_assertions.h". This allows NPNR_ASSERT to be used safely in any header file. - Types defined in "archdefs.h" are now available without including BaseCtx/Arch/Context. This means that utility classes that will be used inside of BaseCtx/Arch/Context can be defined safely in a self-contained header.

* Replace DelayInfo with DelayPair/DelayQuadgatecat2021-02-194-86/+48
| | | | | | | | | | | | | | | | | 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.

* Remove isValidBelForCellgatecat2021-02-164-58/+32
| | | | | | | | | | | | | | | | | This Arch API dates from when we were first working out how to implement placement validity checking, and in practice is little used by the core parts of placer1/HeAP and the Arch implementation involves a lot of duplication with isBelLocationValid. In the short term; placement validity checking is better served by the combination of checkBelAvail and isValidBelForCellType before placement; followed by isBelLocationValid after placement (potentially after moving/swapping multiple cells). Longer term, removing this API makes things a bit cleaner for a new validity checking API. Signed-off-by: gatecat <gatecat@ds0.me>

| * nextpnr: Add base virtual functions for non-range Arch APID. Shah2021-02-051-84/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | This makes the Arch API clearer and also allows a base implementation of functions to reduce the amount of complexity to get a basic Arch up and running. Currently this only implements these for functions that don't return a range. Range-returning functions will require more work in order due to the current 'duck typing' approach (probably a struct that contains the range types combined with templating.) Signed-off-by: D.

| | | | | | | This makes the difference clearer between the general arch API that everyone must implement; and helper functions specific to one arch. Signed-off-by: D. Shah <dave@ds0.me>
* ecp5: Implement IdStringList for all arch object namesD. Shah2021-02-024-85/+66
| | | | | | | This is a complete implementation of IdStringList for ECP5; excluding the GUI (which you will have to disable for it to build). Signed-off-by: D. Shah <dave@ds0.me>

* ecp5: Proof-of-concept using IdStringList for bel namesD. Shah2021-02-025-37/+45
| | | | | | | | | | | This uses the new IdStringList API to store bel names for the ECP5. Note that other arches and the GUI do not yet build with this proof-of-concept patch. getBelByName still uses the old implementation and could be more efficiently implemented with further development.

| | | | | | | | | | 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>
