 You have now gone from newb to hardware hacker in a mere 15 minutes, your rate of progress is truly astounding!!!
 
-BTW: if you want to be a real hardware hacker, it just can't be done with open source tools as of 2018. The root obstacle is that link:https://en.wikipedia.org/wiki/Semiconductor_fabrication_plant[Silicon fabs] don't publish reveal their link:https://en.wikipedia.org/wiki/Design_rule_checking[design rules], which implies that there are no decent standard cell libraries, which implies that you can't get decent power performance and area estimates, see: https://www.quora.com/Are-there-good-open-source-standard-cell-libraries-to-learn-IC-synthesis-with-EDA-tools/answer/Ciro-Santilli The only thing you can do with open source is purely functional designs with Verilator, but you will never know if it can be actually produced and how efficient it can be.
