◆ CreatePinList()

void NETLIST_EXPORTER_BASE::CreatePinList ( SCH_SYMBOL aSymbol,

protectedinherited

Find a symbol from the DrawList and builds its pin list in m_sortedSymbolPinList.

This list is sorted by pin number. The symbol is the next actual symbol after aSymbol. Power symbols and virtual symbols that have their reference designators starting with '#' are skipped. if aKeepUnconnectedPins = false, unconnected pins will be removed from list but usually we need all pins in netlists.

◆ eraseDuplicatePins()

void NETLIST_EXPORTER_BASE::eraseDuplicatePins ( )
protectedinherited

Erase duplicate pins from m_sortedSymbolPinList (i.e.

set pointer in this list to NULL).

(This is a list of pins found in the whole schematic, for a single symbol.) These duplicate pins were put in list because some pins (power pins...) are found more than once when in "multiple symbols per package" symbols. For instance, a 74ls00 has 4 symbols, and therefore the VCC pin and GND pin appears 4 times in the list. Note: this list MUST be sorted by pin number (.m_PinNum member value) Also set the m_Flag member of "removed" NETLIST_OBJECT pin item to 1

Build up a string that describes a command line for executing a child process.

The input and output file names along with any options to the executable are all possibly in the returned string.

Parameters
aFormatStringholds:
  • the name of the external program
  • any options needed by that program
  • formatting sequences, see below.
aNetlistFileis the name of the input file for the external program, that is a intermediate netlist file in xml format.
aFinalFileis the name of the output file that the user expects.
aProjectDirectoryis used for P replacement, it should omit the trailing '/'.

Supported formatting sequences and their meaning:

  • B => base filename of selected output file, minus path and extension.
  • I => complete filename and path of the temporary input file.
  • O => complete filename and path of the user chosen output file.
  • P => project directory, without name and without trailing '/'
