WDC supplies the 65xx brand processor family WDCTools for use in developing PCB (Chip), ASIC (Manuallly Optimized GDSII Hard Core and Verilog RTL Soft Core), and FPGA (Verilog RTL Soft Core) product solutions. These tools support ROMable embedded code and in-circuit debug of control and application software.

WDCTools are provided for use in development of products that feature 65xx processors from WDC and its licensees. They are NOT for reverse engineering of our technology in any form and is NOT provided for development of commercial products that use non-WDC 65xx processors in Core or Chip form.

WDC now provides it's WDCTools suite for FREE. You can register and download at WDC65xx.com.
The base installer includes limited versions of our W65C02 and W65C816 C-Compilers/Optimizers. You can now register and download FULL versions for free from the same WDCTools download page. We have these as individual downloads so that we have a better view of how many people are using the Assembler versions and C-Compiler versions.

WDCTools consist of the following tools:

The Terbium Integrated Development Environment (TIDE) integrates the WDC 65xx tool suite to maximize and ease your use of our tools and is included with our WDCTools. TIDE will help you get started and in no time at all you will be writing, compiling, and debugging your 65xx code!

The WDC W65C02S 8–bit ANSI Standard C Compiler with Optimizer has been validated with the Plum–Hall validation suite. This C compiler can be used with both WDC and WDC's licensed 8–bit microprocessors and microcontrollers.

The WDC W65C816S 8/16–bit ANSI Standard C Compiler with Optimizer has been validated with the Plum–Hall validation suite. This C compiler can be used with both WDC and WDC's licensed 8/16–bit microprocessors and microcontrollers.

The W65C02S Simulator is used to simulate the functionality of the W65C02S Chip, W65C02S GDSII Hard Core, and W65C02SRTL Verilog RTL Soft Core on your PC and is integrated with the Debugger. The Debugger provides window to watch all microprocessor internal registers, data windows for viewing simulated memory, and debug capabilities to step through code and monitor the behavior of your application using unlimited software and a hardware breakpoints. In addition, the Debugger can download and debug control and applications software to your hardware through a TIDE port. An example of a parallel (fast) TIDE port with supporting monitor can be found in our PCB Design Kit and WDCTools.

WDCLIB is a utility program that manipulates libraries of object modules. WDCLIB makes it possible to create a library of commonly used functions.

The WDCSYM utility provides a means to examine symbol files generated by the WDCLN linker.

The WDCOBJ utility provides a means to examine object modules created by the WDCxAS assembler. WDCOBJ will print out the size and type of each section defined in the module, the names of all symbols defined or referenced by the object module, and if desired, each of the data records in the file.

The 65xx Assemblers for the W65C02S and the W65C816S translate assembly language source files into object files.

Since the assemblers do not generate output files the Linker is the program that combines object modules and produces the final object code output in various selected forms for your target.
