| * | synth_xilinx: Merge blackbox primitive libraries. | Marcin Kościelnicki | 2019-11-06 | 1 | -7/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | First, there are no longer separate cell libraries for xc6s/xc7/xcu. Manually instantiating a primitive for a "wrong" family will result in yosys passing it straight through to the output, and it will be either upgraded or rejected by the P&R tool. Second, the blackbox library is expanded to cover many more families: everything from Spartan 3 up is included. Primitives for Virtex and Virtex 2 are listed in the Python file as well if we ever want to include them, but that would require having two different ISE versions (10.1 and 14.7) available when running cells_xtra.py, and so is probably more trouble than it's worth. Third, the blockram blackboxes are no longer in separate files — there is no practical reason to do so (from synthesis PoV, they are no different from any other cells_xtra blackbox), and they needlessly complicated the flow (among other things, merging them allows the user to use eg. Series 7 primitives and have them auto-upgraded to Ultrascale). Last, since xc5v logic synthesis appears to work reasonably well (the only major problem is lack of blockram inference support), xc5v is now an accepted setting for the -family option. | ||||

| * | xilinx: Support multiplier mapping for all families. | Marcin Kościelnicki | 2019-10-22 | 1 | -1/+7 |
| | | | | | | This supports several older families that are not yet supported for actual logic synthesis — the intention is to add them soon. | ||||
| * | Makefile: don't assume python is called `python3` | Sean Cross | 2019-10-19 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | On some architectures, notably on Windows, the official name for the Python binary from python.org is `python`. The build system assumes that python is called `python3`, which breaks under this architecture. There is already infrastructure in place to determine the name of the Python binary when building PYOSYS. Since Python is now always required to build Yosys, enable this check universally which sets the `PYTHON_EXECUTABLE` variable. Then, reuse this variable in other Makefiles as necessary, rather than hardcoding `python3` everywhere. Signed-off-by: Sean Cross <sean@xobs.io> | ||||
