for the design dct_mac : https://github.com/QuickLogic-Corp/ql_designs/tree/00046926f286d008294c46dafe6884d957629c38/dct_mac/dct_mac.v
Resource utilization:
for qlf_k4n8 :
CLB: 88.0 FF: 51.0 IO: 54.0

But when used for qlf_k6n10
CLB : 1 FF : 1 IO : 27
There is wide difference and looks like yosys is optimizing/removing some part of the design

The issue is caused by a bug in the ql_dsp pass of the ql-qlf plugin. Working on fixing it.
