How to import Hspice (PC) simulation data to Matlab (PC)?

[edajason]

I intended to generate the data file from Hspice and plot the figure in matlab. In unix, we know the matlabe can load the hspice data. How to do it in PC version.

Thanks

Have figured it out. Anyone interested, do a google search. and download necessary matlabe file.

Hi Edajason,

Can you share the detail information on how you go about importing HSpice output files into MATLAB. I need this information to plot INL/DNL/SFDR etc in ADC Design.

Thanks in advance

you can use the hspice matlab tools

hi fun.zhao,
how do i add the HspiceToolbox,
i follow the document,but it doesn't work.
thanks in advance.

You have to compile the load command, just read the instruction. As long as you can load the data in matlab window, you will be fine.

Follow the instruction, compile the command loadsig; and then you can load the data:
x=loadsig('eye.tr0'); %Load the hspice output file eye.tr0 into matlab variable x
lssig(x) % List the variables in the x datastructure
y=evalsig(x,'v_3'); % Assign the hspice variable v_3 to matlab

Now you can plot whatever you want.

You may need to use .print command to print out the variables. Then use text editor to manuplate the date for Matlab

use vmware an port

I have a error.I see loadsig is a loadsig.C.
Do I want to have a C++?
Or just use matlab.
Thanks.

you must add ".options post=1" in your spice file.

In command window,type mex loadsig.c then choose 1.

From the paper of HSPICE Toolbox for MATLAB by Michael Perrott, it tell us to add the included files directory to the Matlab path. that is, add a patth to the file startup.m.
where is the startup.m file? It should be made by myself?

how do i add the HspiceToolbox,
i follow the document,but it doesn't work.

how to compile the command loadsig;
did anyone can tell me detial about it



>> x = loadsig(’test.tr0’);
??? x = loadsig(’test.tr0’);

Error: Missing variable or function.

In command window of matlab, type 'mex loadsig.c' ,don't include " ' "

Good luck!

oh my god!!

why ??
it 'still can't work


>> mex loadsig.c

C:\MATLAB701\BIN\WIN32\MEX.PL: Error: 'loadsig.c' not found.

??? Error using ==> mex

Plz confirm your loadsig.c of location.

sorry !anybody can tell me

what's wrong
help me please

how to do this step


All files should work across different computer platforms, though the loadsig mexfile may
need to be recompiled. It is currently compiled for Sun, Redhat Linux, and Windows
2000/Xp machines. To compile the loadsig function for a different platform, go to the
directory containing loadsig.c within Matlab, and then type mex loadsig.c within Matlab.

For example, my hspicetoolbox locates at C:\hspicetoolbox then you must switch your matlab working directory to C:\hspicetoolbox.

Then type mex loadsig.c , choose 1 to complete the setup.

For example if I want to see the transation result of inverter, I need to type that command as shown below.

x = loadsig(’directory of inv.tr0’);
lssig(x)
plotsig(x,’v_in; v_out’)

Re: How to import Hspice (PC) simulation data to Matlab (PC)

Hi, guys

I have a problem when I want to see a DC sweep file like "x.sw0".
Sometimes I can use the flie "x.sw0" extracted by Hpsice. Sometimes
I can not and the error message from Matlab is the following. However,
I could see the transient result extracted by Hspice.

1.
One or more output arguments not assigned during call to 'C:\hspicetoolbox_232\HspiceToolbox\loadsig.dll'.
2.
error in 'init_SpiceData': mxCalloc call failed -
not enough memory!!

Wish someone can help me out.

Thanks in advance
