Standard design constraints or Synopsys design constraints contains the timing and power related constraints which control design w.r.t to the spec. SDC contents: #Clock definition: To define clock, we need following four mandatory informations. 1. Clock source: it can be…
The Unified Power Format (.upf) is an IEEE standard which is used to define the power and related aspects of multi voltage design. UPF contains supply set definition, power domain definition, power switch definition, retention cell definition, level shifter cell…
The timing library (.lib) is an ASCII representation of the Timing, Power and Area associated with the standard cells. Characterization of cells under different PVT conditions results in the timing library (.lib). The delay calculation happens based on input transition…
The Physical Library or Library exchange format (LEF) is an ASCII representation of the abstract of the standard cells. LEF file contains all the physical information of the cells (Technology and Macro cells) and nets. It also contains the Layer…
The Design Exchange (DEF) file is an ASCII representation of physical information of the design. DEF contains Property definition, Die area, Row definition, Physical cell definition, STD cell definition, special net, regular nets, port, blockages, module constraints etc. Def File…
Also known as a gate-level netlist. It contains all the gate level information and the connection between these gates. It can be flat or hierarchical. Flat Netlist contains only one module with all the information. Hierarchical netlist contains a number…
Before going into all the physical design inputs in details, I want to make you understand the block level design and Full Chip Level design (FC). Mostly, partition owners are assigned with the block-level design to work on one partition…
