03/04/2022, 7:24 PMIs this a real dieshot? Or generated from the GDS files? The I/O ring looks real, but the red and purple on the die are confusing me.

03/04/2022, 10:40 PMHuh. thats really cool! Is the flash colored and the regular pattern of the SRAM reflects flash from a specific angle? Or is the color due to interference effects with the regular spacing of the SRAM lines?
