How to Modify the primitive in netlist or How to create own primitive ?

kabalee

Hi Team,

i have some clarification. (i need to translate netlist from OrCAD schematic to Expedition )

i created symbol with Part Number in Orcad_CIS but while generate netlist i could see  primitive(Part Number) associated with footprint. how to keep part number only. or how to remove it in library itself (with out modify the netlist)

Part Number : MIC2544A-1YM

symbol name :MIC2544A-1YM

Cell name : SOIC_0008_0500X040

i have not idea how to remove marked one from library.


primitive 'MIC2544A-1YM_SOIC_0008_0500X040';
pin
'1':
PIN_NUMBER='(1)';
PINUSE='UNSPEC';
'2':
PIN_NUMBER='(2)';
PINUSE='UNSPEC';
'3':
PIN_NUMBER='(3)';
PINUSE='UNSPEC';
'4':
PIN_NUMBER='(4)';
PINUSE='UNSPEC';
'5':
PIN_NUMBER='(5)';
PINUSE='UNSPEC';
'6':
PIN_NUMBER='(6)';
PINUSE='UNSPEC';
'7':
PIN_NUMBER='(7)';
PINUSE='UNSPEC';
'8':
PIN_NUMBER='(8)';
PINUSE='UNSPEC';
end_pin;
body
PART_NAME='MIC2544A-1YM';
JEDEC_TYPE='SOIC_0008_0500x0400_127';
VALUE='MIC2544A-1YM';
end_body;
end_primitive;
END.

    By default Capture creates device type/Device Name Primitive by concatenating source package_footprint..etc.
    If you wants to have any specific value as device Primitive type then you can add property name "device" with required value to symbol, this value will get transferred as device type to PCB Editor/ Expedition
     

    To modify the existing Primitive, perform the following steps:

    1. Select the component in the schematic design, launch Property Editor by right-clicking and selecting Edit Properties.
       


     

    1. In Property Editor, select the filter Allegro PCB Designer or Capture PCB Editor.
       


     

    1. Define the required value of the DEVICE property in Property Editor, which needs to be transferred or modified in Allegro PCB Editor.
       


     

    In the above image, the value of DEVICE property is defined as "Nitai".

    1. Now, Save the design and create the netlist, primitive will changed to Nitai.
