Hi every one,
I have written a code for a simple digital circuit in HSPICE (Like a NAND gate). The width of PMOS and NMOS transistors is Wp, Wn, respectively. Now, I want to do the following steps.
1- Adjusting Wp and Wn using MATLAB.
2- Running HSPICE simulation using MATLAB.
3- Importing HSPICE simualtion results (like the computed power) to MATLAB.
Would you please help me?
And also how should I define "Wp" and "Wn" in HSPICE? Is it true to define them using ".param Wp, Wn" command?
Thank you
There are some beautiful videos, that may provide a very nice clue related to your query: https://www.mathworks.com/videos/cosimulating-spice-models-with-simulink-68726.html

It will be better for you to use Particle swarm optimization(PSO) algorithm for better performance parameters (such as power, delay or PDP).
Dear All,
Thank you Mr. Muhammad Ali, Mr. Syed Shahbaz Hussain for your responses.
Mr. Muhammad Ali, I saw the links you attached for videos, but there was not any video related to my question. What is the problem?
Also I read the paper you suggested. In that paper the link between MATLAB a HSPICE has been introduced, but the MATLAB codes have not been mentioned. I'm looking for MATLAB commands to do this. Especially a MATLAB command to run simulation of a *.sp file in HSPICE. Can you help me?
Mr. Syed Shahbaz Hussian, before to use PSO algorithm, I need to know how to:
1- Read the *.sp file by MATLAB and change a parameter.
2- Run HSPICE simulation by MATLAB Commands.
3- Read the simulation results and extract important outputs like power or delay.
Can you help me?
There are some forum discussions in the web about my question like bellow. But I couldn't do what they have been told.

These videos are great Muhammad Ali !
Hello Majid,
you can do that with the following steps:
1- Create a HSPICE netlist file (.sp) using MATLAB file functions
2- Run HSPICE from MATLAB with MATLAB Dos command
Ex: dos('START /WAIT C:\synopsys\Hspice_Y-2006.03\BIN\hspice.exe - C:\Research\Netlist.sp');
---When the above command was running, MATLAB compiler waits until HSPICE simulation is complete
3- Read HSPICE results (.lis) with MATLAB and extract results by REGEX commands
Ex: str2double(Recognizer('path_to_Netlist.lis','vth'));
Best Regards
