# DRIVE

Drive strength depends on current IOSTANDARD, e.g.

The minitest contains a csv target which generates a csv with differences across all LVCMOS and LVTTL standards for all supported DRIVE strengths and both slew rates.

# IOSTANDARD

Effects bits, TBD exactly how
Sample output:

diff LVCMOS33.bits LVTTL.bits
< bit_00020026_006_00
> bit_00020026_006_08
