I was wondering if anyone could reccomend a viewer for the above mentioned
file format? (preferrably free)
I have Orcad and GC-Prevue but neither of these semm to be up to the job,
regards

where can i find conversion from ibis to pspice libraries or software (downloads)

hello sir,
i am using PHILIPS IC 74AHCT138 and 32  in our project
i require pspice libraries of these ic's
could you please send immediately to the below mail id

Anybody here knows if any version of gEDA was or will be ported to Windows?
At their site there's only a very old version(from 2002) avaliable.

Awhile back someone mentioned that they had a program that was *free*
that could create PDFs.
A friend has a need for such a program, but my surfing/googling hasn't
yielded an answer.

An HSpice to PSpice CMOS Library Converter has been added to the Tool
page of my website.  (Courtesy of Brian Hirasuna of the Cadence PSpice
Support Team.)

Hi to all.
I was wondering if it is possible to measure impedances directly with
programs
like LTspice or Orcad.

Currently i have a PCB board which i need to improve on. However,
i've lost all the scematics and gerber files on it. I understand that
to recover the schematic, i need to reverse engineer the board. Is
there any equipments or software that can help me to recover the

I need some software that will simulate and let me view any circuits I want
to build. I have used software called Crocodile Clips but i need a free
piece of software for home. Can anyone help?
Many Thanks

the following line
R_R_B         0 N01640 10k TC1=100u T_MEASURED=25
generates an "Invalid number" error. If I ommit the T_MEASURED=25
statement, everything works fine.

hai
i am new bee to orcad, is there any web that have some tutorial for
orcad relase 9 ie, for capture,pspice etc
regards

How do I give an input to a circuit in PSPICE Lite 9.2 that is the sum
of 3 sine waves?
Normally for one sine wave I would do something like
V1 1 0 AC 1 SIN(0 .006 1E3 0 0 30)

              After extract layout, the capacitance is too large to
believe. When I used DRACULA LPE to extract layout, there are only about 6~8
capacitors extraced(0.xxxE-14~E-15), but Calibre PEX got about 24~28
capacitors, and their capacitance value is too large to believe( ...

When I using TSMC 0.35 2P4M process to layout, the DRC error report
these messages:
1. POLY Minimum Density Area across chip / CHIP Area must be >= XX%
2. M1 Minimum Density Area across chip / CHIP Area must be >= XX%

I have a 1086-1094MHz monopole antenna mounted on a small ground
plane.
I would like to modify the ground plane so that it sees only signals
in a cone from 45° above horizon and upwards.
