I am not sure if there is sth wrong with the file path/to/hspice/meta.cfg,
pls dump it there,
you can check hspice_integ.pdf for the specific way to integrate hsp into ic61
I did not modified the meta.cfg file, and just integrated it as the brochure says. And if I run the netlist by spectre once, then I can run it by hsp in second without any errors, so it really confused me.
