input buffer overflow, can't enlarge buffer because scanner uses REJECT

[janboeye]

hi,
When write_verilog tmp.v after synth :fine and then read_verilog tmp.v，“input buffer overflow, can't enlarge buffer because scanner uses REJECT” is reported.

tmp.v size is about 300MB.

what's the right command to write out intermedia result?

Thanks a lot!

To directly write the Yosys internal representation to disk, you can use write_rtlil and then read it back in with read_rtlil.
