2.4.5. Creating New Part Types

Typically, new TPart's are not created manually. Instead, they are created by entering the component pinout in a part text file, also known as a part file. A Support Tool, pt_to_h uses the information in the part text (.pt) file to generate a C++ include (.h) file.

Like most of CBOLD, part creation is best explained by example. Below is a user-created part file,

// Part file for 74F07 Buffer Driver
$PART_NAME 74F07                // hex buffer driver
  VCC5 14;                      // 5V power supply
  GND 7;
  A[5:0]  13 11  9  5  3  1;    // inputs
  Y[5:0]  12 10  8  6  4  2;    // outputs

To generate a .h file from this .pt file, the user would run pt_to_h.exe from the console as follows:


You do not typically execute pt_to_h on individual files. Instead, you execute a batch file that runs pt_to_h on all .pt files in the CBOLD parts directory. For example, see make_parts.bat, which is distributed with the CBOLD parts library.

The class declaration that pt_to_h generates from file appears in file 74f07.h as follows:

class CP_74F07 : public TPart {     // hex buffer driver
  port   VCC5;     // 5V power supply
  port   GND;
  port   A;        // AR_BUS(5,0)  // inputs
  port   Y;        // AR_BUS(5,0)  // outputs
  CP_74F07() {
    ...            // constructor details omitted for clarity
  virtual void Register() {
    ...            // Register() details omitted for clarity

This example illustrates the most commonly used features of part files. Other examples can be found by perusing the CBOLD part library. Detailed documentation is in the pt_to_h section of this reference manual.
