Creating a Netlist
ASCII File Format
The ASCII format files for PowerLogic and PADS-Logic V4.0 are organized into sections,
beginning with a keyword enclosed with an asterisk.
The first section starts with *SCH, and gives the system set up parameters for the circuit.
The second section, starting with *CAM, lists the default settings for the plot and printing
outputs.
Following this, all of the data for each sheet is grouped together in the *SHT* section.
This data starts with *CAE*, listing the window zoom setting and cursor location for the
sheet. Other sections are:
*TXT*
Free text items in the sheet.
*LINES*
2D line items, including library entry.
*CAEDECAL*
Description of the CAE symbol decals for all parts in the sheet.
*PARTTYPE*
Description of the part types that appear in the sheet.
*PART*
List of all parts, including their attributes, that appear in the sheet.
Gates and connector pins are each listed separately.
*BUSSES*
Description of busses in the sheet, including the bus name and
location.
*OFFPAGE REFS* List of all off-page flags in the sheet. This includes power and
ground symbols and bus connections.
*TIE-DOTS*
List of all tie-dots in the sheet.
*CONNECTION*
List of the connections in the sheet, with the signal name and path.
*NETNAMES*
List of all net names that are displayed in the schematic.
After all sheets are listed, the file ends with *END*.
Creating a Netlist
You can create a netlist compatible with PowerPCB Version 2.x or PowerPCB Version 3.0.
·
PowerPCB V2 output can optionally include Value & Tolerance information.
·
PowerPCB V3 output can optionally include Part Attribute information.
·
Both formats support optional output of design rules with trace width, individual
sheet selection, and hierarchical symbols inclusion.
