Abdul I would be glad to provide you with a very large design that chokes Protel and makes snails pace look like a rabbit. Viewing time for a backplane pcb takes upwards of 1 hour just to bring it up on a 600 Mhz machine, Of course upgraded our pcs just handle large designs like these. A fresh netlist import can take 4 - 6 hours. After using the synchronizer on medium designs , we gave up on that avenue about a year ago. I m not shaking my doodads by stating my boards are bigger than anyone else's but I do know the synchronizer, will choke for days when we attempt to use it. Simply reloading the netlist over a current netlist will take an entire day maybe until the next morning. We cut that time down to about 4 hours by clearing first. I am not exaggerating as I would be glad to provide you with as many different designs as you would like to attempt to load. We even killed Spectra with two designs. >Further, the clear process is unnecessary.< Our Clear, load, connect, run drc method has come to us thru long coffee breaks while waiting for Protel to catch up. I'm not knocking the program, because I have never used any other program for designs this large therefore, I don't know how they would respond either. I would imagine any program would be slow, its alot of stuff to remember. Both the netlist load and synchronizer, will go off to Thailand before the pc responds to any options, We cant tolerate that as we have lost too many man hours waiting. We hit Cntl ALT Del then tried another way in until I found out four step recovery program (joke) I found clear to speed things up, the difference in load times dropped from minutes vs hours on medium size boards with maybe 1500 components Connect Copper... Well....You are sort of right .. you may have to do a little work , re-assign split planes and polygons, when you use the connect copper command. The DRCs will catch it, it is the last of my four steps to recovery. The four steps work without failure, every time. I do not trust a netlist load without clearing first because as we all know we don'ts know which cycle even or odd the load is on.
