Designing flipflops with python and migen hackaday. That is, they operate on numbers normally, but instead of treating that number as if it were a single value, they treat it as if it were a string of bits, written in twoscomplement binary. At each iteration, the bit is applied from the left to the right.

There are following bitwise operators supported by python language. The licenses page details gplcompatibility and terms and conditions. The resulting file can uploaded into a spreadsheet for easy bit by bit analysis. In this case, the original series is the characters since you can iterate over strings in python, which gives you the characters that make up that string, and the new series is a set of characters with the 0s and. Im trying to take a binary number in string form and flip the 1s and 0s, that is, change all of the 1s in the string to 0s, and all of the 0s to 1s. To form 5, you start with 0101, flip all the bits to get 1010, and then add 1 to arrive at 1011.
