FPGA Editor

The FPGA editor is a graphical application used to display and configure your FPGA designs. You can perform the following functions with the FPGA Editor.

• Place and route critical components before running automatic place and route tools on an entire design.
  
  
• Modify placement and routing manually. The editor allows both automatic and manual component placement and routing.
  
  
• Read from and write to the Physical Constraints File (PCF) to create and modify constraints.
  
  
• Verify timing against constraints.
  
  
• Create physical macros (.nmc files)
  
  

Editing operations performed within the FPGA Editor change the configuration of the design and also change the design database. Editing functions include selecting, adding and deleting objects, viewing and changing object attributes, copying components, swapping components and net pins, placing components, and routing.

The FPGA Editor has its own set of commands, many of which can be customized to suit your work style. You can access these commands from the pull-down menus, user toolbar, command macros, hot keys and aliases, or by entering the commands on a command line within the FPGA Editor window.

In addition to customizing commands, other FPGA Editor tools may also be tailored to your needs. For example, you can do the following.

• Decide what commands are performed when the FPGA Editor window first opens
  
  
• Choose the colors for different objects (for example, components) and areas (for example, the push button panel or command area) in the FPGA Editor window
  
  
• Use command macros and hot keys
