I'm trying to programmatically update a Qspice netlist. I read the *.net file in using fileread.
netlist = fileread([filepath filename);
the file looks like this:
L5 N08 0 {Lp} Rser = 0.01 ic=0
L6 0 N07 {Ls} Rser=0.01 ic=0
V2 N06 0 pulse -VGA VGA 0 3n 3n period/2 period ac=1
L1 N11 0 {Lp} Rser = 0.01 ic=0
L2 0 N10 {Ls} Rser=0.01 ic=0
V1 N05 0 pulse -VGA VGA 0 3n 3n period/2 period
.tran 0 {duration} {starttran} 2n
.param Cp = 1/(Lp*(2*pi*fres1)^2)
.param Cs = 1/(Ls*(2*pi*fres2)^2)
.param starttran = duration-4m
.save I(L5) I(L6) v(n05) i(L1) i(R2)
.step param fsw list 81750 83000 85000 86400
fileread brings this in as one big character array.
I want to programmatically replace the .step param line with a new one, as a loop through my code and update some of these parameters.
I can find the index into the char array where ".step param" occurs, but I can't figure out how to convert the characters from .step to the end of that line to a string so I can just replace the whole line with a new one, or to smartly count the characters from .step to the end of that line (those characters change, so I can't just look for a match) and just replace those characters in the array.
Thanks in advance for the help.
