Logic FridayFree software for boolean logic optimization, analysis, and synthesis
Logic Friday is a freeware tool for students, hobbyists, and engineers who work with legacy digital logic circuits based on standard IC packages.
Current version: 1.1.1, released 11 September, 2009. What's new. With Logic Friday you can:
Enter a logic function as a truth table, an equation, or a gate diagram
Enter functions with up to 16 inputs and 16 outputs
Minimize a function with options of fast or exact minimization
Automatically generate a multi-level gate diagram using gates chosen from a library
Automatically minimize the number of standard gate packages
Trace the logic state of each gate's inputs and outputs for a given input vector
Compare logic functions
Generate new functions as logical combinations of others
View any function as a truth table, equation, or gate diagram
Generate efficient, compact C code lookup functions from logic functions
Save functions and gate diagram images to files
Export and import truth tables as CSV files for editing in spreadsheet applications.
Logic Friday uses espresso for minimization and misII for gate diagram synthesis.* Both programs are included with the download.
