Synthesis and Technology Mapping
Log from VHDL/Verilog to Discrete Logic Flow
This is where things get a bit more interesting. I was concerned that it was quite difficult to coerce Yosys into using my custom gate libraries, but in fact it was rather easy. The "cmos" example proved to be an excellent blueprint to creating a custom...

Fun with Harmonics: VHF from a Serial Port
Log from Serial Port SDR
I measured the edge rates on the TTL output of some of these USB-UART bridges to be under 2ns. This generates some strong frequency harmonics, which you can see here in the 67th harmonic of a 1MHz square wave output by an FT232RL driven by the...
