Implementation Improvement Overview

ISE

After implementing your design and analyzing implementation results, you can use the following methods to improve your design performance prior to programming and configuring your device:

Optimize timing performance, using any of the following methods:
- Use synthesis techniques, such as proper coding, as described in Using Synthesis Techniques to Improve Timing Performance.
- Use timing constraints, as described in Optimizing Design Constraints.
- Floorplan your design, as described in Floorplanning with PlanAhead™ Software.
Experiment with implementation options, also known as process properties, using any of the following methods:
- Modify individual process properties, as described in Design Performance Techniques for FPGAs.
- Use predefined Design Goals and Strategies provided to modify sets of process properties, as described in Using Design Goals and Strategies.
- Use SmartXplorer to run multiple implementation flows using different sets of process properties, as described in Using SmartXplorer.
Use FPGA Editor to make modifications to your FPGA design.
You can use FPGA Editor to check that your design was implemented as expected, and then use it to fine-tune your design, as described in Implementation Strategies using FPGA Editor.
Use techniques to reduce area utilization, power consumption, memory use, and runtime and to preserve design results as follows:
- Use coding techniques to reduce area utilization and power consumption, as described in Using RTL Coding and Synthesis Techniques to Reduce Area Utilization and Power Consumption.
- Use constraints and process properties to reduce memory use and runtime, as described in Memory Use and Runtime Strategies for FPGAs.
- Use SmartGuide™ technology to use results from a previous implementation to guide the next implementation. This helps to reduce runtime, preserve logic, and meet timing, as described in Using SmartGuide Technology.
- Use Partitions to reuse or preserve certain modules in your design during implementation, as described in the Partitions Overview.
