retiming, net splitting and driver replication) for timing need to be done after placement, not during synthesis. Physical synthesis is a dead feature for 3rd party tools, since it's long become clear that netlist modifications (i.e.

If you look at Precision RTL Plus then you'll notice the feature list doesn't mention quality of results, but other things, like encryption, tool integration, analysis, etc. In most cases, it produces exactly the same results. Regarding the performance of Precision, I'm not aware of any benchmarks where it outperforms the other tools. Neither Precision nor Synplify are big money makers anymore, and they are pretty much static tools now. Precision is gathering dust at a lot of companies, and Synplify is usually kept to a single license, reserved for compiling very difficult cores where an extra 5% timing margin is needed. Synplify, Synplify Pro, Synplify Premier, and Synplify Premier with Design Planner User Guide December 2005 Synplicity, Inc. Over time, both Altera and Xilinx made a lot of progress in their toolset, to the point that they both became the default tool for their respective products. Back in the day, the Altera & Xilinx synthesis tools were somewhat lacking, and Mentor and Synplicity made good coin on upgrading synthesis tools.
#VIVADO USE SYNPLIFY PRO SOFTWARE#
I guess other companies could try to reverse-engineer the information, but for now, you'll have no choice but to use the FPGA vendor software for P&R.Īfter synthesis and P&R, you have a binary file that is ready to be "downloaded" into the FPGA.That's a good question. P&R is always done by the FPGA software from the FPGA vendor, because FPGA vendors do not publish enough information about the internals of their devices to allow any other company to create P&R software.
P&R can take a few seconds for a small FPGA, or a few hours for a big one.
If the problem with your design lies at the top-level or is fundamentally hardware-related, using ChipScope modules is probably the best way to debug them. Place-and-route (P&R) describes several processes where the netlist elements are physically places and mapped to the FPGA physical resources, to create a file that can be downloaded in the FPGA chip. Using ChipScope, you can capture almost any signal in your system, including top-level signals. These designs typically consist of 1000s of source files and implement the equivalent of a multi. Step 3: Create DCPs for the Black Box Created in Synplify Pro. Today, we are seeing more FPGA-based prototyping systems being used to verify huge ASIC designs. By Angela Sutton, staff product marketing manager, FPGA Synthesis, Synopsys. This will obviously cause problems as your processor will probably not function without this component inside it. A Simple Way to Use DesignWare Libraries in FPGA-Based Design Prototypes. 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 Synplify Pro.ĭoing the synthesis using a third-party software usually yields better-optimized netlists (put more and/or faster logic into your FPGAs). Explanation: Synplify thinks that this module in your design is not being used to generate any useful output, and in order to make the design more efficient, removes it during synthesis. Synthesis takes your design (HDL or schematic) and creates a flat netlist out of it.Ī netlist is just that, a "list of nets", connecting gates or flip-flops together.įlat means the netlist doesn't have a hierarchy it's one big file with all the nets in it (but the net names might still reflect the hierarchy of your original design). The FPGA software major task, in addition to facilitate design-entry, is to synthesize and place-and-route your design.
