Segmentation fault (core dumped) when performing PnR

[Arthuuuuroo]

Hello,

I was trying to do PnR but I'm facing a segmentation fault.

I'm using this command: ./nextpnr-xilinx/nextpnr-xilinx -l sim_dir/nextpnr.log -v --debug --no-tmdriv --freq 12 --ignore-rel-clk --ignore-loops --chipdb flow_puf/xc7s50csga324-1.bin --xdc flow_puf/ro_puf_new.xdc --json sim_dir/ro_puf_s7.json --write sim_dir/ro_puf_s7_routed.json --fasm sim_dir/ro_puf_7.fasm --router router1

I got this error:

"Clock 'uart_rx_inst.clk' can be driven by:
$iopadmap$ro_puf_s7.clk$intcell$IBUF.OUT delay 0.200ns
Segmentation fault (core dumped)"

Based on the stack trace, the program encountered a segmentation fault (SIGSEGV) in the function nextpnr_xilinx::Arch::getPortTimingClass, specifically when attempting to access a variable or object at an invalid memory address.

The problematic line is indicated as being in the file arch.cc at line 1228. Relevant details from the stack trace are:

0x0000aaaaaabc86fc in nextpnr_xilinx::Arch::getPortTimingClass (this=0xaaaaaad46f00,
cell=0xaaaaae0b2910,
port=<error reading variable: Cannot access memory at address 0xffffff7fffe8>,
clockInfoCount=@0xffffff800068: 0) at /home/adrien/nextpnr-xilinx/xilinx/arch.cc:1228

Could anyone provide insights into what might be causing this issue or suggest steps to resolve it?

Thank you!
