I’ve got silicon on the brain, so I’m going to give a die shot another go at name that ware. Hopefully this one is a bit easier than the last one. This excerpt is a design pattern I look for and find on almost every SoC. It’s technically showing a bit more than just the part I’m focused on, so as a hint I’m primarily interested in identifying the structure towards the lower left corner of this image. If you’ve seen one of these before, you’ll know what it is – it’s pretty unmistakable, and a design pattern that’s highly conserved across processes, nodes and foundries. Bonus points to anyone that can explain some of the reasons why things are organized the way they are! Posted in name that ware | 7 Comments » The Ware for June 2026 is an SGI RM6-64 raster manager, from a KONA/InfiniteReality graphics system. Congrats to Christian for naming it! email me for your prize. This gem of a board was gifted to me by someone at SGI back when I worked there in…I want to say 1998? I even still hav
Name that Ware, August 2026 August 30th, 2026 The Ware for August 2026 is shown below. Technically, this is an integrated circuit – just from a very different era than last month’s ware! Posted in name that ware | 7 Comments » Winner, Name that Ware July 2026 August 30th, 2026 The structure in question for last month’s ware are a pair of NPN transistors that form the core of a bandgap voltage reference circuit. As its name implies, a bandgap voltage reference generates a near-constant voltage for use inside chips. The voltage is intended to be fairly constant over process variations,…
