Programming

I’ve had a love of programming since my first real summer internship back in 1999. Over the years I’ve programmed in Visual BASIC, PHP, Ruby, Perl, C#, SKILL, Ocean, Verilog-A, C++, BASH, AWK, VHDL, SPICE, MATLAB, ASP, Java, C, SystemC, Verilog, and probably a few I’ve forgotten. These days, it’s usually Python, C and C++.

2019-now Python front-end to ciccreator – Python

2009-now Rapid layout generation tool for SAR ADCs – C++

2017 Power meter blink to kWh using nRF52 – C/Python

2015 Ocean script support package – Perl

2004 SystemDotNet.Report – C#

2005 SystemDotNet: mixed-signal, discrete time, event driven simulator – C#

2003 Time Tracker 2 – C#

2001 NextGenLab.Chart – C#
