This paper describe a rapid backend process flow (synthesis, placement, STA, routing) and top level integration to implement a small RTL IP into a tapeout ready chip using the Efabless online platform . The full process is completed in less than 3 hours. The IP implemented is a configurable frequency divider
DRC is something which (most likely) is supposed to fail in first instance. Let’s see what you do to fix them. In below eg. drc count is 25. Qrouter (an open-source router, which will be discussed in detail in webinar) is really good with some standard cell sets like the one which comes distributed with qflow, like OSU018, they are really nice one’s to work with. All the ports have nice squares, they don’t have these inside ‘L’ corners as shown below.
