Build & Run Your Own CPU With CRUMB 1.3

Developed by Mike Bushell, CRUMB Circuit Simulator is the perfect platform for building and testing fully functional and real-time simulated circuits. With its extensive range of components and features, CRUMB provides valuable insights into various aspects of modern electronics, making it an excellent tool for complementing real-world prototypes.

Simulation speed has long been a limiting factor in CRUMB's development, but this update is reported to significantly overcome that barrier. According to the developer, CRUMB is now over 20,000% faster, opening up new possibilities for more complex and efficient circuit designs.

Mike Bushell has previously shared that it was Ben Eater's series on building an 8-bit CPU that inspired him to create CRUMB with the vision of allowing users to build their own designs. With the latest update, that idea has now become a reality.

You can download Mike's 8-bit CPU design, which is ready to be programmed, but before you do, the developer highly recommends building your own CPU first. It took him about three weeks, from building the clock module to running a simple program, and he encourages others to dive in and experience the process for themselves.

In addition to the main improvements in CRUMB 1.3, several bug fixes and changes have been implemented to enhance the overall stability of the program, including:

• Recognition and handling of Matrix errors;
• All component models checked and verified for floating lead connection errors;
• Re-work of the audio system to deal with the new circuit frequency levels;
• Minor procedural fixes with editing, loading, and saving;
• Arduino interpreter procedure altered to synchronize with the new circuit speeds;
• Performance increased.
