As I'm approaching finishing my first pcb design using 16.5, I have a few questions concerning netlist generation and loading into the board file.
Throughout the board design process, there are occasions where I will need to change the schematic necessitating a new load of the netlist. Coming from the 16.2 and older generation, all I would need to do was "autoECO" the new netlist into the pcb file and keep on trucking.
The process in 16.5 I have to follow is this: (Starting with both Capture and PCB Editor open)
Close PCB Editor
Select the Netlist command in Capture
Pick my board file
Input my output file
Select "Open board in PCB Editor"
This will generate the netlist and open the board in Editor. This seems to be more "manual" then in previous (16.2 and prior) versions. I was not expecting to have to close PCB Editor and manually input the new board file name.
So this begs the question, am I doing this the hard way? Can you have the netlister run while the board file is open AND increment the file name? Older versions would automatically append a -1, 2, etc.... to the board file name.
Hi Tom, nice to hear you got your first board done in 16.5 thats cool. The learning curve on Allegro even for a seasoned pcb designer is a hair-pulling experience. On the up side if you look at the changes Cadence has made since the Allegro 16.2 release and where they are now with 16.6 I think great progress has been made.
Going forward I think they need to get a handle on how they handle libraries for PCB Footprints. As it is right now and if you look at competing tools the lack of a solid Library tool that has good integration with the creation of PCB footprints is a truely glaring omission in my honest opinion. Even the older Layout tool was way better in this regard.
The auto ECO in the older Layout tool was very nice. That took a bunch of grunt work out of the packaging and update process. The import Logic feature in Allegro is kind of similar to that but the only difference is that you have to bit twiddle the files in capture at the front end.
