Cannot place part - Pin numbers do not match

gburnham

Hello, I'm fairly new both to Cadence and to PCB design in general.

I'm attempting to make a fairly simple design - it's pretty much just a cable in a PCB form.  The only hiccups are the tight size and the traces are impedance controlled, but I haven't gotten there yet!

I'm attempting to place the connectors - one I got from Samtec's website (ERM8-030-XX_X-X-DV.dra & .psm) and the other is also a Samtec one, but I had to make the footprint, as they haven't uploaded it yet.  I'm using Allegro Design Entry CIS v16.5p003 for my schematic and Allegro PCB Designer v16.5 for my layout. 

I'm having problems placing the ERM8 connector (but mine places just fine!).  Every time I try to place it (Place>Manuallly...) I get the error "E- (SPMHGE-82): Pin numbers do not match between symbol and component. Run dev_check on device file for more information."

I've looked in the symbol, and there are 60 electrical pins and 2 mechanical pins (just like the one I made), and they're all numbered from 1-60 like they should be (mechanical pins are not numbered). 

The dev_check script is supremely less than helpful - it says it has saved a dev.check.brd file, but no such file exist on my hard drive (I searched the entire thing).  Also, the only "error" the log file mentions is very cryptic:

Netlist File Name: 'dev_check.net'      Layout File Name: 'dev_check.brd'

===========================================================

$PACKAGES
!* ; U1
 ^
ERROR(SPMHNI-60): Device name not found, line ignored.
-------------------------------------------------------------------------------
$END

I have no idea what this means, and I'm getting very frustrated.  I've gone into my connector footprint and deleted all of the pins, saved everything, then created an entrely new set of padstacks and made pins with those new pads - no luck. I'm pretty sure I've set both my pad and psm paths right (I got an error about them before this one, which went away).  However, it's a pretty new install for our systems, so perhaps I don't have some other environmental variable or something configured correctly?

 Thanks in advance!

    How about your schematic symbol? Make sure your schematic symbol has the same number of pins as your PCB footprint. Also make sure you dont have some overlapping pins on the schematic symbol.
