Import SPICE Raw File

Import a SPICE raw file into MATLAB.

Description

There are two functions enclosed that can quickly read the raw file output of SPICE. This can be used to dump the entire contents of a SPICE simulation into MATLAB for further processing. This version works in a similar fashion to a prior post (rawspice6.m), but reads files an order of magnitude faster. This function can read files of > 30Megs in less than 30 seconds.

The first function imports the data into a structure where each node is indexed by its node name (ReadRawSpice). The second function imports the data into a cell where each node name is indexed by a number (ReadRawSpice2). Otherwise, the two functions are identical. Both are in the same .m file, so the user should separate them out after download.

This cannot import PSPICE .dat files from Cadence, 10.3.0 p001. The format is apparently proprietary, rather than the ASCII expected by ReadRawSpice.

[Scott Miller]

The proprietary format for PSPICE from Cadence, 10.3.0 p001, can be avoided by using the File..Export..text option, rather than the probe format.

[Alan Curtis]

Good idea; but the line

s=importdata(filename);

does not create s.textdata or s.data variables in MATLAB Version 7.3.0.1266 (R2006b)

[Francesco Riganti Fulginei]

it's refered to a particular spice version...

[seenivasan sundararajan]

More information are needed along with the file.Means where to store the file etc..

You could try the SignalStorageToolbox (http://homes.esat.kuleuven.be/~scoseman/toolboxes/SignalStorageToolbox/index.html), which supports (specific output formats of) DC and TRANSIENT simulations of at least hspice, eldo, spectre, ultrasim and aps.
