This is the Mixed signal digital test pattern macro i created. It creates hundreds of thousands of commented lines of test patterns for comparing pass fail, capturing data and making analog measurements in a matter of seconds from only a few hundred lines of my opcode/operand command sets, which cover all tyypes of patterns and die communication protocols. This saves weeks of coding, produces good pattern compiles immediately, creates a record and good for debug with design.

1. L. Snowden Software to create Mixed Signal Test Patterns
This is the mixed signal pattern generator that I wrote in Excel Vbasic.
This particular page of 180 lines of my opcode operand commands creates 25,000 lines of commented digital patterns in Manchester
encoded format. I have opcodes for reading writing, judging P/F digital data, inserting microcode automatically to make analog
measurements, etc etc.
I have all the codes, Manchester, I2C, S/PIDF one wire, one pin and I can add any other protocol quickly, few days max.
