What is DC synthesis?
DC Ultra™ RTL synthesis solution enables users to meet today’s design challenges with concurrent optimization of timing, area, power and test. Additionally Design Compiler Graphical produces physical guidance to IC Compiler, place-and-route solution for tighter correlation to layout and faster placement runtime.
What does design compiler do?
Design Compiler prints combinational and sequential (i.e., non-combinational) circuit area into the *. area file. Compile your design in ncverilog (or vcs) before synthesizing it because Design Compiler may not tell you a thing even if your design has a serious verilog problem!
What is Dc_shell?
Design Compiler is the command line interface of Synopsys synthesis tool and is invoked by either typing dc_shell or dc_shell-t in a UNIX shell. The dc_shell is the original format that is based on Synopsys’s own language while dc_shell-t uses the standard Tcl language.
What is synthesis flow?
Synthesis is process of converting RTL (Synthesizable Verilog code) to technology specific gate level netlist (includes nets, sequential and combinational cells and their connectivity). Goals of Synthesis. To get a gate level netlist. Inserting clock gates. Logic optimization.
What is IC Compiler?
IC Compiler is the industry leading place-and-route system for established and emerging process technology node designs. > Multicore support throughout the flow delivers improved productivity.
What is RTL compiler?
RTL Compiler is an HDL synthesis software from Cadence.
What is uniquify in Design Compiler?
The command uniquify is used to make unique the instances of the same reference design during synthesis. We can now apply different ‘constraints’ to each half adder, without affecting the other instance of it in the design.
How does design compiler graphical help accelerate synthesis?
To accelerate synthesis, Design Compiler Graphical includes scalable multicore infrastructure that delivers significant runtime speed-up on multicore compute servers, yielding 2X faster runtimes on four cores.
What does Synopsys do in the design compiler?
Design Compiler Graphical includes Synopsys’ virtual global-routing technology that enables designers to predict wire-routing congestion during RTL synthesis.
How does design compiler graphical work with IC Compiler?
Design Compiler Graphical uses technology shared with IC Compiler to take these physical effects into account to achieve superior quality of results. The innovative optimizations of Design Compiler Graphical work in conjunction with place and route technology to deliver 5% faster timing on high performance designs.
How does the design compiler help RTL designers?
RTL designers also gain access to IC Compiler’s design planning capabilities from inside the familiar Design Compiler synthesis environment. They can perform what-if exploration to identify and fix floorplan issues early and achieve an optimal floorplan.
