[PEDA] P98 SE Schematic ERC for Electrical Pin Types
OK; basic question: In P98 SE, how do you configure the electrical types of pins to be input/output/power/passive/unknown etc. such that in schematic you can do such things as run an ERC and find nets that don't have an output? How exactly do you initiate such an ERC? How can you override noted conditions that are really acceptable ones such that you don't have to keep rummaging through them every time? NOTE: One of my customers masters all his schematics exclusively in Protel 98 SE using flat topology and is not about to change, so I must use it for the schematic tool in this particular case. It is not practical to convert to DXP and back for each minor change. Jeff Condit 6946 Clark Rd.

I also changed Tools-ERC-Setup-Net Identifier Scope to 'Net Labels and Ports Global' which got rid of 16 pages of input errors and warnings flagged because they were only connected to a port symbol.

Re: [PEDA] P98 SE Schematic ERC for Electrical Pin Types
I set the options for Unconnected Ports within the connection matrix for the 8 cells where * Port crosses Unconnected? Now ERC shows unconnected ports. Does Protel sometimes flag more than one error at the same location? If so, how can No ERC Directives correctly identify which error to not report? Is there any way to change to electrical type definition of a pin on the schematic? PLDs with hundreds of pins intrinsically designated as I/O regardless of programming give rise to a very large number of warnings, such as an IO=Output clash. If I could, for example, magically change and I/O pin to an input where applicable it would make these errors go away. However, since the same PLD part type is used in many designs with different programming, I don't want to change the pin definitions in the library. What about nets with no outputs? How can these be checked to make sure they are what is wanted? For example, when 2 boards are interconnected in a system, one could have only an output (and connector pin) while the other has only inputs (and a connector pin). Is there any way to check that Port directions make sense with regard to pin electrical types? For example, the port should point into an input and away from an output? Jeff Condit 6946 Clark Rd.

Re: [PEDA] P98 SE Schematic ERC for Electrical Pin Types
You mean P99SE, yes? Or do you mean P98? Pin types are defined at the component level, and the part editors are used to define these characteristics. Once the target part has been brought into the part editor, it's simply a matter of doublwe-clicking a pin, then examining the resultant pin-edit window to determine and/or modify its electrical type.

Re: [PEDA] P98 SE Schematic ERC for Electrical Pin Types
Hi AJ! I meant P98SE. I guess what I was balking at was not being able to reconfigure a pin's electrical type from schematic. The reason is that generic PLDs don't really have an electrical type until they are programmed. Then the pins can become inputs, outputs, tri-state, or whatever you want. If in the library they are all just set to I/O, then the schematic reports a lot of warnings and can miss some errors. If you know what you want the pins to be (which is only sometimes the case) and can set the pin electrical types accordingly, then the ERC is much more meaningful. This could be done in the parts editor, but then the part would be wrong on other designs where the pins are used differently. Thus, the desire to be able to characterize them in schematic. Anyway, that was the thought.

Re: [PEDA] P98 SE Schematic ERC for Electrical Pin Types
I found the Tools-ERC menu option. I think I missed it first time around because I was not on a schematic document at the time. So this answers the portion regarding how to initiate ERC. I also found Place-Directives-No ERC which is used to mark things like unused inputs. This is helpful, but doesn't do the job an override does. Still looking for input on this subject.

Re: [PEDA] P98 SE Schematic ERC for Electrical Pin Types
Thanks Peter. That's what I like to do as well, but its takes a little more time to do and the customer is not always willing to pay for it. In this particular case, the customer made it the way it is and wants it that way, so the customer gets what the customer wants.
