Analog has always been difficult, a bit of a black art persuading a digital process to create well-behaved analog circuits, capacitors, resistors and all the rest. In the distant past, we would solve this by putting the analog on a separate chip, often in a non-leading-edge process. But modern SoCs integrate large amounts of digital… Read More

Probably everyone knows that openAccess is a layout database. It was originally developed at Cadence (called Genesis) but has since been transferred to Si2. Strictly speaking, openAccess is actually an API and the database is a reference implementation. The code is licensed under a sort of halfway to open-source: you can use … Read More
