I would definitely go with a P4. The 1G ram seems to be plenty. In my
previous job, we were running Allegro and SpecctraQuest as well as Spectra
on P4 machines with 512M ram without problems. The largest boards had 22-24
layers and up to a thousand components. I'm not an expert on Spectra but
that seemed to take the most time to run. Sometimes we used 2 to 3 machines
in parallel by constraining the areas for routing. Some runs would go over
night.

HI

Can any body tell the system configuration required for Allergro and
spectra.

The existing one with P3 and 1gb ram is working very slow for bigger jobs

Anybody suggest.

resend the message:

I think the description of [path description]section of the ebd file is not
detailed enough.I got confused when I meet such condition:
Node A
Len=0 L=2 C=1
Node B

Should I represent it like this:


B <---@@@@@----------|--------------->A
L=1 |
|
=== C=1
|
---
or like this:


B <-------|------------@@@@@------------>A
| L
|
|
=====C
|
---
By the way,should the capacitor be connected to ground or power? How to
determine this ?
In fact , I found many cases like the above one in the DIMM ebd file
supplied by molex.
Maybe both representation is just the same? Or there is some description I
did not noticed?Or this is really a oversight?
any response will be appreciated.
