The design does not synthesize.

[Place 30-574] Poor placement for routing between an IO pin and BUFG. If this sub optimal condition is acceptable for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING. However, the use of this override is highly discouraged. These examples can be used directly in the .xdc file to override this clock rule.

Hi， Can someone solve this problem? I run into this problem too.

I have added "set_property CLOCK_DEDICATED_ROUTE FALSE [get_nets jtag_tck]" to the file and build it well. But the DBG IP did not work well when I tried to connect the device.

Hi @zhuzhizhan,

to my knowledge, this Cores-SweRV_fpga repo hasn't been well maintained recently.

Please look at https://github.com/chipsalliance/Cores-SweRVolf for a well-maintained alternative.
