This is my port of IRSIM-CAP to Linux.
IRSIM-CAP is an improved version of IRSIM which includes some code
to do power estimation through toggle counts.
The original version of IRSIM-CAP was based on IRSIM version 9.0
and is available by anonymous ftp at:
infopad.eecs.berkeley.edu/pub/irsim-cap.tar.Z
The present version of IRSIM-CAP is instead based on IRSIM version 9.2
and hence includes the fault-simulator IFSIM.
Note:
There is also an IRSIM version 9.3, vailable by anonymous ftp at:
gatekeeper.dec.com/pub/DEC/magic/6.4/irsim-9.3.tar.Z
which includes power estimation (see the files README.irsim9.3 and
man/irsim9.3.powerEst.doc)
IRSIM-CAP, however, provides some interesting features not found in
IRSIM version 9.3, see the file man/irsim-cap.doc
Further modifications with respect to IRSIM-CAP version 9.0:
1) (file src/irsim/rsim.c) the command sumcap now yields:
(a) the sum of all capacitances minus Vdd and Gnd capacitances
(b) Vdd and Gnd capacitances
2) (file src/irsim/rsim.c) the command vsupply has been added to calculate
power dissipation, like IRSIM 9.3
The default value of vsupply is 5V
3) (file src/irsim/rsim.c) the command sumeffcapcap now yields:
(a) the total effective capacitance charged from 0->1
(b) the elapsed time from the last zeropower command
(c) the total power dissipation of captraced nodes:
Pd=Ceff*Vsupply*Vsupply/Telapsed
4) (file src/irsim/rsim.c) the command capreport now yields also
the power dissipation of each captraced node.
5) (file src/ana11/postscript.c):
the user name is printed in the banner.
To compile IRSIM-CAP run the make_irsim script.
To install IRSIM-CAP set CAD_HOME to whatever is appropriate in your system and run
the install_irsim script.
To make the fault simulator: first use the make_irsim script to build IRSIM-CAP,
then (before cleaning anything in irsim) run the make_ifsim script.
To install IFSIM-CAP set CAD_HOME to whatever is appropriate in your system and run
the install_ifsim script.
Note that in this distribution, in the bin/ directory, there is already a
binary version of IRSIM-CAP and IFSIM-CAP, obtained by using
gcc ver. 2.5.8 (Linux ver. 1.0.9)
