Spartan-6 FPGA Design Assistant - Using optimization features from third-party synthesis tools
The following Answer Record discusses how optimization features can be used from third-party synthesis tools to help optimize your design.
NOTE: This Answer Record is part of the XilinxSpartan-6 FPGA Solution Center (Xilinx Answer 44744).The XilinxSpartan-6 FPGASolution Center is available to address all questions related toSpartan-6 devices.Whether you are starting a new design withSpartan-6 FPGA or troubleshooting a problem, use theSpartan-6 FPGA Solution Center to guide you to the right information.
Some third-party synthesis tools, such as SynplifyPro,have optimization features that can help to improve performance with your design.For more information on synthesis tool settings that should be utilized,see theHDL Coding Practices to Accelerate Design PerformanceWhite Paper(WP231): http://www.xilinx.com/support/documentation/white_papers/wp231.pdf
Following is a list of sections in this white paper that specifically mention the different synthesis tool settings:
"Maximize Block RAM Performance"
"Use of I/O Registers"
"Replicate Registers with High-Fanout"
"Nested If-Then-Else, Case Statements, and Combinatorial For-Loops"
