PCF file error trying to access IO_32, IO_33 and IO_43 (SFBIO IOs) #17

Closed timsaxe closed 4 years ago

timsaxe commented 4 years ago

I get the following message: PCF constraint "set_io blueled 22" from line 4 constraints net blueled of a block type PB-BIDIR to a location for block types: PB-SDIOMUX

The test example is located at qorc-sdk/qf_apps/qf_helloworldhw/fpga/rtl

It works when blueled is assigned to 38 (which is really the blueled) but if the PCF is changed to point to 22 then it fails. The test PCF is:

set_io redled 34 set_io greenled 39 //set_io blueled 38 set_io blueled 22

I haven't done an exhaustive test, but I suspect that any IO 32 or greater will have the same issue.

I've fixed the issue with https://github.com/QuickLogic-Corp/symbiflow-arch-defs/pull/137. Basically the PCF file and PART type were not passed to the Yosys wrapper script. This caused the plugin that converts cells for SDIOMUX not being run.
