The acquisitions of Virage Logic by Synopsys in 2010, have allowed building a stronger, diversified IP port-folio, including the embedded SRAM, embedded non-volatile memory and embedded test and repair solution. Looking back in time, I remember the end of the 80’s: at that time the up-to-date solution to embed SRAM in your ASIC… Read More
The problem:To move dual-port SRAM library and macros from a 40nm process to a 28nm process. In addition to all the changes between two different foundry processes, the 28nm rules are disruptive and incompatible with the previous rules. The memory corecells (foundry-specific) would also need to be completely replaced.
Current… Read More
One of the most demanding areas of layout design has always been memories. Whereas digital design often uses somewhat simplified design rules, memories have to be designed pushing every rule to the limit. Obviously even a tiny improvement in the size of a bit cell multiplies up into significant area savings when there are billions… Read More
