XILINX.PFF Property Filter File Format

The xilinx.pff property filter file, located in $XILINX/cadence/data, specifies what properties SIR2EDF (called by CONCEPT2XIL) writes out to the EDIF netlist from your Concept schematic. The xilinx.pff file also specifies the format of these properties should when they write out to the EDIF netlist.

The xilinx.pff file has sections for symbol, pin, and net properties. Each section begins with a property section header record of the form, $xxx_PROP.

For symbol properties this header record is $SYM_PROP.

A list of properties that you can legally place on symbols in Concept follows the header.

Similarly, for pin properties, the header record for the pin property section is $PIN_PROP, and the header for net properties is $NET_PROP.

Each section also ends with a property section END record, $END.

Curly braces specify comments, as illustrated in the following example.

     { This is a comment in the property format file. }

You must provide a property specification record for every property that you want SIR2EDF to recognize and write out to the output EDIF file. The syntax of the property specification record follows.

     property_name:    "property_format"     property_cast    property_type;

• property_name - the name of the property as used in your design
  
  
• property_format - depicts the appearance and format of the property when written to the EDIF file (case-sensitive specification)
  
  
• property_cast - the data type of the property value. Valid cast types follow.
  
  
  • Boolean (valid property values are TRUE or FALSE)
    
    
  • Integer (valid property values are integers)
    
    
  • Real (valid property values are real numbers)
    
    
  • String (valid property values are alphanumeric strings);
    
    
• property_type - the SIR2EDF type of the property, used by SIR2EDF to determine how to handle the property. The only valid SIR2EDF property type for Xilinx properties is NORMAL.
  
  

The following example shows the syntax using string.

   loc:            “LOC”           String  NORMAL;

In the example, the “loc” property (found in the $SYM_PROP symbol properties section) has a property_name of “loc.” This property writes out to the EDIF file as “LOC=value,” where “LOC” is in upper case, and ”value” is some alphanumeric string.

As with all Xilinx properties, the SIR2EDF type is “NORMAL.”

The following example shows the syntax using Boolean.

   keep:            “KEEP”              Boolean  NORMAL;

In this example, the Boolean property “keep,” from the $NET_PROPS section, attaches to a net. Specify its value as either TRUE or FALSE in the input design. When written out to the EDIF file, it appears as “KEEP=TRUE.”

The standard xilinx.pff property filter file shipped with the M1 Cadence Concept interface resides in $XILINX/cadence/data and is listed below.

NOTE

The properties commented with the notation, “{For lblox_syn}” only support netlisting of Cadence Synergy Verilog designs which target LogiBLOX library components. Properties labelled as “{Not entered by user}” generate internally by Xilinx tools only.
