Enjoyed the article. I worked in Australia back in the late 80s and we had Touchstone and Academy later. Thoroughly loved using them for microwave circuit design ( amplifiers and passive circuits ). Still used to use rubylith then and had to buy that silly diamond head cutter and ruby from the states. Used to have a great time with the EESOF team writing bug reports ( even visted EESOF once when back packing trip from Australia - very nerdy !! ). When series 4 came it was hard to get used to but we used it ( altghough I seemed to remember many did not make the switch and kept the older versions ) - microwave engineers getting angry at SW - now there's a sight. We had Eagleware also but used it for the filter synthesis tool
Now I use AWR at work but I am evaluating ADS - ADS is the best !!!! Love it( and I have used Ansoft also ) !!!! Still learning lots and still enjoy circuit design even after 20 years.
