Hi,
I edit the dcf file by hand to get the sequence of operation points
printed the way I want to. When I read the dcf into the corner tool, the
sequence of printed and plotted performance measurements are listed in
no particular order. This is irritating when I want to have a certain
sequence of parameters for documentation purposes.
To get a feeling about what I want:
Performing corner simulation on process and supply voltage I want to
have a table check on the DC-operating points in an open loop gain
simulation. For a simple OPA it would be something like:
p0_gm p0_gds n0_gds p1_gm p1_gds n1_gds A0 A1 A
where
A0 = -p0_gm / (p0_gds + n0_gds)
A1 = -p1_gm / (p1_gds + n1_gds)
and
A = A0 * A1
Now, when I read in my carefully handcrafted dcf file this sequence is
garbled. I have to read the file into excel to move the columns right.
Has anybody had the same problem and found a solution to it?
