This question may seem strange to you, but it is of very huge
significance for me.
Can we predict, if a circuit will simulate or not looking at the matrix
formed?

I am a licensed user of Protel 99 SE and have used it for a few years on
several computers. Recently, I bought a new computer and tried to load
my software on the machine. It will load but will not allow me to unlock
the software. I know I,m doing it right, and the user codes are ...

Can you please help me out with a few answers about modified nodal
analysis.
I have read the book by Kishore Singhal and Vlach.
1. Does MNA(modified nodal analysis) solve non-linear circuits too?

It is really strange that Endiannes is not dependent on the Bit_Order
but only on the Byte_order.
But, Why  the Bit_Order has not been taken into consideration ??
Really strange. Any specific reasons for this ??? Eager to know about

I'm simulating a Sigma-Delta modulator in Hspice and I get the
following error:
*error*:  maximum conductance on node     0:ecompar          =(
0.0000D+00)

Hi, anyone know how can I import .cir files in Microwave office?I have
some output files form HFSS in .cir format but I tried with import
functionality and is not possible import them  due a syntax problem
(seems)

Hi. I want to learn how to use spice.
To get to know spice I want to start simulating a simple schema:
--| R 1 | --

  I was trying to get "Spice 3 implementation guide" from the past few
days. I searched through the berkeley site & did a lot of searches on
google. But I could not find this document anywhere.
Can anybody please help me in finding it.

I'm currently developing a PCB featuring a Xilinx Virtex-4 device. Unlinke
the Virtex-II series they now offer the possibility to route various clock
signals to several domains on the FPGA and select them locally by specific
clock multiplexer inputs.

A coworker needs to update an Orcad schematic to change the net names
on hundreds of signals to FPGAs.  He is looking for a way to do this in
an external tool (like an editor) by exporting the net list and then
updating the schematic with the revised net list.  I could not tell him

How many companies have some kind of electronic simulation and what is
there software called. What one should I learn?

I need some help in analysing singular matrices. Actually I am trying a
build a tool which will identify circuits which give rise to singular
matrices. Can anybody please suggest me circuits which may give rise to
a matrix (with dependent rows or columns). I need this to test my ...

Hi, anyone know if there are some softwares that can convert file *.cir
(from Orcad Spice format) to *.sch?
Thanks

I am doing a quick survey on PCB schematic / layout tools used.  If you
have a couple minutes could you answer the following questions and
email me at thepcbd...@yahoo.com.  I will post the results of the
survey.
