Hi there, I have a very short question. Is there any possibility to write a data inside a txt file? How can i write GBW, DCG and PM in a txt file? I tried in this way but these are values, not vector.

.control
  ac dec 100 1 10G
  settype decibel out  
  *setplot ac1
  meas ac GBW when vdb(vout)=0
  meas ac DCG find vdb(vout) at=1
  meas ac PM find vp(vout) when vdb(vout)=0
  
  set wr_vecnames
  set wr_singlescale
  wrdata tb_openloop.txt GBW DCG PM

You need to add this command

set filetype=ascii

in order to write data in txt file.

it is not a problem this option. I get this txt, but i don't want all this line. i just need one time the parameter. frequency GBW DCG PM 1.000e+00 2.479e+07 6.291e+01 6.081e+01 1.012e+00 2.479e+07 6.291e+01 6.081e+01 1.023e+00 2.479e+07 6.291e+01 6.081e+01 1.035e+00 2.479e+07 6.291e+01 6.081e+01 1.047e+00 2.479e+07 6.291e+01 6.081e+01 1.059e+00 2.479e+07 6.291e+01 6.081e+01 1.072e+00 2.479e+07 6.291e+01 6.081e+01 1.084e+00 2.479e+07 6.291e+01 6.081e+01 1.096e+00 2.479e+07 6.291e+01 6.081e+01 1.109e+00 2.479e+07 6.291e+01 6.081e+01 1.122e+00 2.479e+07 6.291e+01 6.081e+01

just add:

print GBW > measure_results.txt

print DCG >> measure_results.txt

print PM >> measure_results.txt
