Drive synthesis to obtain a netlist with very small area.

So, you have completed your RTL, synthesised it and now you have a netlist & constraints. Next comes the physical design part of it;making your design into a representation of the actual geometries you will manufacture. You will do a bunch of stuff here, like floorplanning, placement, CTS, routing, timing closure, physical verification, formal verification etc. The major stages are explained below.

The Precision Synthesis: FPGA Design course will help you understand how to use Precision Synthesis to synthesize your design from HDL RTL to technology specific gate-level netlist.

ASIC synthesis verification from RTL code to final netlist

We will then simulate the synthesized Verilog Netlist that we export from Leonardo, using ModelSim.

Q1. Drive synthesis to obtain a netlist with very small area. You can do thisby setting "" and "" option for "".These is just a suggestion; you can try more options and see how they affectarea of the netlist. Try to obtain best possible timing within that area. Youshould try atleast two synthesis runs to obtain a better timing.

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 should also be part of physical design, but we will skip that for now.


Synthesis process transforms an HDL description to a schematic-like netlist

The gatelevel netlist from the synthesis tool is taken and imported into place and route tool in Verilog netlist format. All the gates and flip-flops are placed; clock tree synthesis and reset is routed. After this each block is routed. The P&R tool output is a GDS file, used by foundry for fabricating the ASIC. Backend team normally dumps out SPEF (standard parasitic exchange format) /RSPF (reduced parasitic exchange format)/DSPF (detailed parasitic exchange format) from layout tools like ASTRO to the frontend team, who then use the read_parasitic command in tools like Prime Time to write out SDF (standard delay format) for gate level simulation purposes.

Synthesis is the process in which synthesis tools like design compiler or Synplify take RTL in Verilog or VHDL, target technology, and constrains as input and maps the RTL to target technology primitives. Synthesis tool, after mapping the RTL to gates, also do the minimal amount of timing analysis to see if the mapped design is meeting the timing requirements. (Important thing to note is, synthesis tools are not aware of wire delays, they only know of gate delays). After the synthesis there are a couple of things that are normally done before passing the netlist to backend (Place and Route)

Synthesis can be done by the FPGA vendor's (free or non-free) software, but can also be done by third-party (non-free) software like .Doing the synthesis using a third-party software usually yields better-optimized netlists (put more and/or faster logic into your FPGAs).

In this tutorial we will be synthesizing Verilog code using Leonardo Spectrum from Mentor Graphics. We will then simulate the synthesized Verilog Netlist that we export from Leonardo, using ModelSim.

Diamond Overview - Lattice Semiconductor

Choose options "All" and "Extract FSM" and click OK. Thisperforms initial mapping of RTL to a netlist. This will take some time based onthe design size. This step can be considered as a coarse level synthesis. Toperform more fine grained synthesis and optimize a design, we setup operatingconditions and constraints to meet various goals viz., performance, area andpower. After performing generic build on the design, you can view the designusing "Schematic" tab of the BG interface.

The Synthesis and Designer Icons are not enabled when a netlist is imported in the Libero. The icons will be enabled when a RTL code or schematic is imported/created.
