PADS Software Netlist Defaults

NOTE: To prevent a designer from editing engineering netlists, please obey the following rules:

1.         Reference Designator Names have a 15 character limit.

2.         Pin Names have a 7 character limit.

3.         Netnames have a 57 character limit.

4.         Illegal characters are *  <  >  ?  :  .  ,  

            Lower case characters are not allowed.  

            Avoid \ / because Unix systems do not accept these characters.

5.         Please use the abbreviation rather than the full name i.e.: use K, not CATHODE. 

            Use A, not ANODE.  

            All new library decals with special alpha pin numbers (IE: NO & NC for switches) must be clearly noted on the data sheet that will be used to create the library decal.

2 & 3 pin devices with alphabetical Pin Names are as follows:

            DIODES                              CATHODE = C

                                                         ANODE = A

            TRANSISTORS                  BASE = B

                                                         EMITTER = E

                                                         COLLECTOR = C

            POWER FETS                     SOURCE = S

                                                         GATE = G

                                                         DRAIN = D

            POTENTIOMETERS          CW = 1

                                                         WIPER = 2

                                                         CCW = 3

            CAPACITORS  &               POSITIVE = 1

            BATTERIES                       NEGATIVE = 2

6.         PADS format netlist is preferred.

7.         Netlist header should be:        !PADS-POWERPCB- V4.0-MILS!

                                                            *NET*

8.         Netlist footer should be:         *END*

9.         SAMPLE NETLIST:              !PADS-POWERPCB- V4.0-MILS!

                                                            *NET*

                                                            *SIG N00001

                                                            U1.1   C1.1   R1.1

                                                            *SIG N00002

                                                            U1.2    R1.2

                                                            *SIG GND

                                                            U1.7   C1.2   U2.7   C2.2

                                                            *SIG VCC

                                                            U1.14   U2.14   C2.1

                                                            *END*

10.       File name suffix must be .ASC if you are using PowerPCB.
