Description
Summary:This paper shows the design flowchart to do metal fix in Chameleon CS2112. CS2112 is an integrated SOC system in one chip with a fabric circuit of 84 processors, 48 local memories, ARC processor, memory controller, PCI controller, DMA configuration subsystems and programmed I/Os. The first silicon failed due to the hold time problem at program I/Os and large IR drop at the center of the chip. The advantage of metal fixes will reduce the mask cost for bug fixing found in silicon. There are a couple of problems to be addressed in the post-silicon metal fixing. Make sure the simulation result in the old design to match the silicon measurement and the simulation setup provides the accuracy for metal fix to predict the performance in new silicon
