short description of fusesoc commands

Fusesoc examples

kind of a "crash course" on fusesoc, the usual commands used during a FPGA development cycle. A good starting point is to watch Olof's presentation at Wosh: https://www.youtube.com/watch?v=HOFYplIBSWM

create library (local)

fusesoc library add <library_name>

where can be a local filesystem or a git repository

"""
numbers of digits vs powers of 2
--------------------------------
plot (and print) in jupyter number of digits used by every power of 2 twom from 0 to 128, e.g.:
2^16 = 65536 (5 digits)
it is useful when converting binary to BCD (Binary Coded Decimal), often used in FPGA/ASIC
(using double-dabble algorithm) development, to convert a number into a human readable format, e.g.:
