Thanks Patrick, I was hoping that if I needed to create device files, that they could be simplified. So Donna from Comcast says that if it is orCAD v10, the schematics can output netlist files specifically for Allegro, it creates the needed pst*.dat files, and separate device files are not needed. Sound right to you? So then the only thing I can see that would need to be done is for the orCAD schematics to be pointing to the same files that Concept points to in order to get the Allegro symbol information. Thanks for helping out! Regards, Gary E.

Look at the two very simple attached examples.

I found out that the schematics are orCAD v10, but I doubt that they are pointing to my Allegro symbols. So, if this is the case, I have to create a device file for each different part (i.e. 0603, sot23, tsop24 etc.), right? I did a library dump on a design I'm working on now, and here is the device file for a 60 pin BGA: (DEVICE FILE: DDR2DRAMX8_60-60) PACKAGE BGA60_8X12MM_0P8MM CLASS IC PINCOUNT 60 PINORDER 'DDR2DRAMX8_60-60' A0 A1 A10 A11 A12 A13 A14 A15 A2 A3 A4 A5 A6 A7 A8 A9 BA0 BA1 BA2 CAS_L, CKE CK_DH CK_DL CS_L DM DQ0 DQ1 DQ2 DQ3 DQ4 DQ5 DQ6 DQ7 DQS_DH DQS_DL NC0 ODT RAS_L VDD0 VDD1, VDD2 VDD3 VDDL VDDQ0 VDDQ1 VDDQ2 VDDQ3 VDDQ4 VREF VSS0 VSS1 VSS2 VSS3 VSSDL VSSQ0 VSSQ1 VSSQ2, VSSQ3 VSSQ4 WE_L PINUSE 'DDR2DRAMX8_60-60' IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN IN, BI BI BI BI BI BI BI BI BI BI NC IN IN POWER POWER POWER POWER POWER POWER POWER POWER POWER, POWER UNSPEC GROUND GROUND GROUND GROUND GROUND GROUND GROUND GROUND GROUND GROUND IN FUNCTION G1 'DDR2DRAMX8_60-60' H8 H3 H2 K7 L2 L8 L3 L7 H7 J2 J8 J3 J7 K2 K8 K3 G2 G3 G1 G7 F2 E8 F8, G8 B3 C8 C2 D7 D3 D1 D9 B1 B9 B7 A8 A2 F9 F7 A1 E9 H9 L1 E1 A9 C1 C3 C7 C9 E2 A3 E3 J1 K9 E7, A7 B2 B8 D2 D8 F3 PACKAGEPROP DEVICE_LABEL 'X8 SSTL2' PACKAGEPROP HEIGHT '0.xxx' PACKAGEPROP PARENT_PART_TYPE DDR2DRAMX8_60 PACKAGEPROP PARENT_PPT DDR2DRAMX8 PACKAGEPROP PARENT_PPT_PART 'DDR2DRAMX8_60-60' PACKAGEPROP PART_NAME DDR2DRAMX8 END Do I really need all of this in the device files (obviously a 0603 device file would be much simpler!), or are there just a few basic things needed? Could I do a library dump on a very large Concept -> Allegro design that uses many different symbols, then use the device files for the orCAD design? Sounds like it could be quite a job creating all of the device files for a pretty good size design!! Thank for the help Patrick! Gary E.

Otherwise, there is a fair amount of 3rd party setup you have to do, including creation of simple device files.

I have been asked to do a small design for Marketing (!?!), and they, for some reason, use orCAD for schematic capture. It has been years since I imported anything but Concept HDL. So in the Import Logic window, Other tab, do you just point to the orCAD netlist (?) in the "Import netlist:" field? Anything else or is just that simple? Thanks for any help! Gary E.
