Examples of errors:

As a simple example to explain. The figure is a circuit diagram:

Then fill in the appropriate component to each PCB footprint. Here, LED lamp selection of in-line package, can be found by its package name in PADS library search for the LED (figure BATTERY package is my own to do it, do not care about it)

Then generates asc network list in a conventional manner, and after opening the PADS, and then introduced into the network asc list file, which pop up when the error ascii.err text, as shown below:

As can be seen from the text, D1 (the LED lamp) 1 and pin 2 are prompted Not valid pin name, so the last two lines of the two warning display connected with D1 are deleted, and if this error is ignored, it You see FIG PCB generated as shown below:

It can be clearly seen here, the LED lamp is not properly connected up.

the reason:

If the LED type open editing interface library from the inside (File -> Library -> input led *, election Parts, found LED -> Edit), then switch to Pins page, you can see the foot Number 1,2 A and K respectively

In OrCAD double clicking the LED D1 on the properties dialog box, switch to the Pins tab, it can be seen that the pin 2 is 1 and Number 2

OrCAD and PADS in LED lights inside of the pin numbers of different and, therefore, led to the error before seen

solution:

If we intend to use this package, you can take the following methods to manipulate:

(Note PADS library LED Part is unable to modify the name of the pin, because even if you can not save modified normal. The same can not be modified directly in OrCAD pin number in.)

Update 2012-8-27:

Can not copy in the library inside the seal turn, create a new element directly encapsulated in the window creation element, see Pin Number is not and 2, are then stored directly to 1, is not the case attention is switched to the General tab, see if selected Define mapping of Part Type pin numbers to PCB Decal, so check itUnchecked.Save it.

2012-08-04

In order not to affect the original library, we will LED elementsPackage (Decal)First copy out

Then the Save dialog box pops up, we save it to usr go inside the library and renamed MYLED, (Again again, we copied a Decal, rather than the Part）

Usr then open the library, you can see MYLED package has been saved in, we create a new element of this package, click the Part, select New ..

In the new pop-up editing interface, switch to the PCB Decals tab, Assign just created package MYLED

Switch to the Pins tab, note the two-pin Number of times this can be modified, if this time is displayed in the Number 1 and 2 respectively, this is the number we need, if not, change it. 1 and 2 can

After clicking the lower right corner of the Save As ..., a new element will also be saved as MYLED, click OK, this time if re-open the Library tab, and switch to Part usr library, you can see we have just created element MYLED the

After doing work here PADS, OrCAD will then switch to the new MYLED D1 is filled in FootPrint

After saving again generated network list, and then import, pop ascii.err file again:

Before you can see the error message all gone, as the text prompt "is not specified or not supported ASCII file version", you can ignore a direct swap.

The new PCB Layout as shown below, can be seen that D1 is connected correctly go up.
