I. NetlistIn & Floorplan II. Placement III. Clock Tree Synthesis IV. Routing After routing, your layout is complete. Now a number of checks are performed to verify that the drawn layout works as intended. Physical …
I. NetlistIn & Floorplan II. Placement III. Clock Tree Synthesis After CTS, the routing process determines the precise paths for interconnections. This includes the standard cell and macro pins, the pins on the block boundary …
I. NetlistIn & Floorplan II. Placement For synchronized designs, data transfer between functional elements are synchronized by clock signals. In a top level digital design, you will have one more more clock sources, like PLLs …
I. NetlistIn & Floorplan After you have done floorplanning, i.e. created the core area, placed the macros, and decided the power network structure of your design, it is time to let the tool to do …
This is going to be a series of step-by-step explanation of physical design flow for the novice. I am going to list out the stages from Netlist-GDS in this session. Of course some say synthesis …
set_timing_derate set_timing_derate is a command that lets you constraint the timing a bit more. The idea and application is simple enough, but you might get confused with all the talk about process variation and OCV …
Creating a dummy .lib file is something every physical design engineer has done now and then. If you have a verilog model of the block available, your task gets easier. The following script automates .lib …
Engineering Change Order or ECO is how you incorporate last minute changes in your design. ECO saves money and time and is prevalent in the industry. When I talk ECO, I am talking about ECOs …
I have been writing an article on ECO flows.Of course I cannot talk about freeze_silicon ECOs without talking about spare cells.When I was a wee intern sitting through PnR training, spare cells confused me. I …
Standard Parasitic Exchange Format(SPEF) is an IEEE format for specifying chip parasitics. The specification for SPEF is a part of standard 1481-1999 IEEE Standard for Integrated Circuit (IC) Delay and Power Calculation System . Latest …
