Physical Design Flow IV:Routing
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… Read more »
Physical Design Flow III:Clock Tree Synthesis
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… Read more »
Physical Design Flow II:Placement
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… Read more »
Physical Design Flow I : NetlistIn & Floorplanning
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…. Read more »
