IndexError placing design with DSP

[eddieh-xlnx]

The attached Interchange netlist is a Yosys compilation of the picorv32 design with ENABLE_MUL and ENABLE_FAST_MUL parameters set to incur use of DSP blocks.

picorv32_dsp.zip

Running this with the interchange_cut1 branch (currently 4696a20) results in:
