ql-qlf plugins: `-no_adder` flag affects cell parameters in output blif

Open coolbreeze413 opened this issue 2 years ago • 0 comments

From this section: https://github.com/chipsalliance/yosys-f4pga-plugins/blob/77fb7b17d96d9d5b1fcfb96711f4787cbf26bc4a/ql-qlf-plugin/synth_quicklogic.cc#L535

The logic is causing the cell parameters in output blif to not be written if -no_adder flag is passed in to synth_quicklogic. We are not sure of the reason behind this logic. Should this logic be removed to always pass the cell parameters to blif?

This affects RAM scenarios, where the MODE_BITS are not appearing in the output blif, in case the -no_adder is set.
