Quartus appears to have had a crush

I able to duplicate the issue and have submitted a case to the engineering team to investigate. I will keep you updated as soon as there is any progress or findings.

Since this is from an older Quartus software, there may be limited resources to fix this issue, and a workaround will most likely be provided. I hope you understand.

p/s: Please keep in mind that any work involving our engineering team may take some time, ranging from a few days to a few weeks, depending on the complexity of the issue.

As of now, I have not received any update from the engineering team.

I will continue to follow up with the engineering team and provide you with an update as soon as possible.

Thank you for your patience and understanding.

Engineering found that the root cause of the error is that Quartus standard incorrectly processes the escaped names of the type

reg [7:0] \cfblk203_reg[0] ;

This is in the file Subsystem_yosys.v

I see that the file is generated bythe yosys tool. yosys may have an option to generate the names differently.

For example, if we change the name to

reg [7:0] clkbuf203_reg_0;

This will be handled properly by Quartus standard.

Dropping a note to ask if the workaround works for you?

Do you need any further assistance from my side?
