This applet simulates a 6x6 cell matrix. It is fully interactive, allowing the user to change inputs on border cells, change the truth table configuration of any cell, and observe all inputs and outputs of all cells. The system clock can also be controlled: it can be stopped, single stepped, or allowed to free-run.
The matrix continually processes inputs and truth tables to produce outputs. If an input to a cell changes, any corresponding output changes occur immediately. Similarly, if you change a truth table for a D-mode cell, the new output values immediately appear.
This simulator is similar in style to the V2.0 simulator for the PC, also available for download from this site.
