Tony Thanks for the feedback. I might work on second revision because I want to elaborate on moving in and out, routing selected nets and components only. To answer your questions: Why not to use the DO file from DXP?.... You can set up all of your design rules inside the PCB file, almost all of the rules will be transferred seamlessly to the router dsn file. There is little need to add effort by writing a long do file. With the exception to guarantee that you wont choke off any routing paths I rarely write more than a few lines in do file. DXP and 99 do an excellent job of maintaining the design rules for the router. DXP has a slight edge with better support for classes. The Do file from DXP is not a usable file, that is why I mentioned not to use it. It can nt be tweaked, there is more information contained in the dsn file. Tweak your design rules in the pcb file. This is where it should be done anyways.
I need to read what I wrote about the MAX vias.. I will respond later this morning to that question Mike Reagan -----Original Message----- From: Tony Karavidas [mailto:[EMAIL PROTECTED] Sent: Saturday, September 18, 2004 3:05 AM To: 'Protel EDA Forum' Subject: Re: [PEDA] Electra router Hi Mike, It's nice to see this published. Figures 2 and 3 need to be swapped or the text needs to be swapped. One page 7, there is a sentence which doesn't make sense to me: "A good rule is to use is maximum via" I tried to make sense of it by continuing to read, but it didn't help. Can you explain what you mean? There is a typo on page 8. (first paragraph, second to last sentence.) How come you say not to use DXP's DO file? Does it generate bad info? Isn't it a good place to start and then manually tweek it? Doesn't DXP communicate the PCB rules into Electra through the DO file, or do the rules migrate through the DSN file? (I thought that was the board layout only) Thanks!
