* Remove the unused CellInfo::pins fieldgatecat2021-02-103-25/+0
| | | | | | | | | | | No arches ever actually used this to implement a Cell->Bel pin mapping, and in practice if any did try they would inevitably hit bitrot. This field had limited use in practice as it is necessary to also support cases where one cell pin maps to more than one bel pin. Removing this old field is the first step towards developing a new API for this. Signed-off-by: gatecat <gatecat@ds0.me>

* Use 'T' postfix to disambiguate LHS and RHS of usingD. Shah2021-02-081-42/+48
| | | | | | | Arches might otherwise have range types named ambigiously with the entry in ArchRanges. Signed-off-by: D. Shah <dave@ds0.me>

* Add pure-virtual ArchAPI interfaceD. Shah2021-02-051-104/+198
| | | | | | | | | This splits out the pure-virtual definition of the architecture API into ArchAPI; leaving BaseArch to only provide default implementations (which can now be completely opted out of by deriving from ArchAPI instead of BaseArch). Signed-off-by: D. Shah <dave@ds0.me>

| | | | Signed-off-by: D. Shah <dave@ds0.me>
* nextpnr: Add base virtual functions for non-range Arch APID. Shah2021-02-051-0/+108
| | | | | | | | | | | | | 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. Shah <dave@ds0.me>
* Add RelSlice::ssize and use it when comparing with signed ints.Keith Rothman2021-02-051-0/+1

* Mark IdString and IdStringList single argument constructors explicit.Keith Rothman2021-02-043-18/+28
| | | | | | | | | 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>
* Use a LRU cache for pip to wire map.Keith Rothman2021-02-031-10/+113
| | | | | | | | This avoids storing the entire pip to wire map in memory with a moderate runtime increase and a dramatic memory decrease (2 GB to 200 MB for A50T). Signed-off-by: Keith Rothman <537074+litghost@users.noreply.github.com>

* ecp5: Implement IdStringList for all arch object namesD. Shah2021-02-023-8/+55
| | | | | | | 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>
* refactor: Replace getXName().c_str(ctx) with ctx->nameOfXD. Shah2021-02-023-9/+8
| | | | | | This makes the ongoing migration to IdStringList easier. Signed-off-by: D. Shah <dave@ds0.me>
* ecp5: Proof-of-concept using IdStringList for bel namesD. Shah2021-02-027-24/+56
| | | | | | | | | | | 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.
