iCE40 is one of the niche-market (in this case, ultra-low-power) FPGAs that your post&#x27;s parent talks about. iCE40 competes primarily with other boutique manufacturers and ancient big-vendor parts like CoolRunner CPLDs, not full-featured top tier FPGAs like Virtex. No Holy Grail of open tooling is going to make up for a lack of essential features which cost hundreds of millions of dollars to develop.
