Anyone know how to load a netlist into a blank pcb?

Anyone here using AutoTRAX EDA software from www.kov.com?
I bought it last weekend and find it to be extremely quirky. For the
price it could be great ($95 US), but there are a million little
problems that make it very frustrating to use.

What is the comment symbol for Eagle's script (.scr) files. "rem"
and ";" in the first column and C's /* ... */ all had no effect. Surely
there is one...

I have a problem with Mentor Graphics - Design Architect.
When I run simulation, the following message shows:
 "Note: Starting up Tcl-DP server ..."
 "Error: Tcl-DP server may not start yet, please try again ......"

Hello people!
Is there any circuit simulation program (like SPICE on the PC) for HP-48
calculators?

I've been trying to look up IC design and can't quite find what i'm looking
for.
I want to know what the shapes look like for transistors and such when they
are drawn in preparation for being transferred to silicon.

I need to use a circuit simulator under a linux O.S. I downloaded LTSpice
( Switcher-CAD III ) and i found a .exe file.
I ask: is there a linux version of LTSpice?
If not can i use LTSpice under wine and how i can do it?

does anyone know where I could get simulation model for Micro
Devices RF2126 high power linear amplifier? Any format would
be fine.
Thanks.

HI every1,
  Iam designig a PCB using orcad(9). At the moment i have two
boards(each is a two layer board). I have almost finished the design.
But i just realised that instead of having two seperate boards it will

where can I find some infos about some limits of spice simulation? I
need it for a comparision of different simulators.
Any link or comment (especially if you've faced a certain problem) is
welcome.

Are there any technical reasons why Micro-Cap 8 shouldn't be bought as a direct
replacement for PSpice? Most of us are keen to ditch the "industry standard",
because, well, we decided today over coffee and buns that we simply don't like
it very much. Don't ask why, it's just us. ...

For multi-gigahertz analysis, a regular Spice model of the chip/die
properties alone is of little use. You need to incorporate the device
package's parasitic properties, too. But these don't seem to very easy
to come by. Does anyone know of any sites where these additional model

I've come across an odd problem in the simplified circuit I'm posting
to a.b.s.e under the same subject title as this message.
I can't seem to get LT to step through 3 drain resistor values whilst
performing a DC sweep of Vgs. It should amount to just 30 iterations

When i install LTspice under wine it doesn't complete the installation and
gives me this error:
Couldn't find startup  Shell Folder location
Can someone tell how i can  resolve the problem?

I'm using Cadint to design and Specctra 9.0 to auto-route.
My problem: Specctra think all holes are plated, even though they are
set as Unplated in Cadint.
I unfortunatly  can not make plated holes in my PCB's.
