[PEDA] SUCCESSFUL CONCLUSION - Autorouter Stability Problems

2002-01-21 Thread John Whittaker
Hi Guys It was extra work, but I exported my PCB file as PADS ASCII (Not Protel ASCII, this didn't fix the problem), then imported it back in. I received a message that 4 entities could not be converted. This must have REALLY worked, because the autorouter has run fine since then. Thanks,

[PEDA] Autorouting or manual routing, or both?

2002-01-21 Thread Matt Polak
Hey folks, It seems that a majority of you are doing some very dense, high-speed layouts with 4-6 layers being quite a common occurrence. I'm just wondering how much you typically route by hand, and how much you let the auto-router whack away at. Being primarily

I usually find that if Protel has got into this sort of routine, then it's time to re-boot the PC (often needing power-cycling, just to make sure). The same applies with Windows 2000, although it's not needed nearly as often as with 95! Regards Andy Gulliver -Original Message- From:

Michael, i had the same problem with Win95 some time ago. Protel did not liked the Microsoft fax printer driver (Exchange) that time. After deinstalling the fax driver protel printed ok. Best way is to deinstall all your printer drivers and reinstall them one by one, checking which of them is the

Matt I am a circuit/system designer who is is self-taught on PCB design. I design my own pcb's because I design portable electronics and the flexibility of placing the components at the time I'm designing the electronic package, etc. gives me some incredibly efficient packaging results. I only

Rooms is a shining light among Protel's features. I lament Altium's dearth of information about its workings, which no doubt leaves many Protel users unaware of its capability. I recall that the few posts I've seen on the subject were positive. Clearly, Mr Lomax appreciates Rooms, and I

A very good website that deals with high speed design is www.signalintegrity.com. It is hosted by Dr Howard Johnston and has articles on specific aspects of PCB design like terminations, bypassing, planes, routing impedance etc.

Dear Matt, Normally I only route the boards by hand (4 6 layers) , my expierence with autorouting utillities (not only Protel) is that you still want to change tracks which you don't like so you will wind up re routing the whole board :) The only thing i sometimes use the autorouter for is
