IBM releases RTL source code for A2I Blue Gene/Q processor core

It&#x27;s great that companies do this, but I wish that they would also open-source the verification infrastructure at the same time.<p>Otherwise, anyone who wants to use it in a commercial setting has to either re-do their own verification effort and due-diligence, or just trust the core works perfectly. Don&#x27;t get me wrong, I trust IBM to build a working CPU, but that doesn&#x27;t mean there aren&#x27;t corner cases to be found when you put the core in a new SoC environment.<p>There is lots of open source HDL out there. We need re-usable verification infrastructure too!

This should be interesting. Probably far too complicated for me to understand, but will still take a look. Surprised to see VHDL instead of Verilog, but not complaining at all.<p>edit: Just took a look. Code is nice and clean but complicated was an understatement.

&gt; It is a 27 FO4 implementation,<p>Am I out of touch, or is that an extremely long cycle? I thought CPUs were generally something like 14-15 FO4.

Composed of VHDL and Tcl source code, nice to see them pursuing the right path. :)

Good news! But will it be sufficient to reverse declining popularity of the POWER architecture?
