13.25.17.2.1 Checking the Physical Design Constraint (PDC)

Abort Compile if errors are found in the physical design constraints: Changes the “Abort on PDC error” behavior. Select this option to stop the flow if any error is reported in reading your PDC file. If you deselect this option, the tool skips errors in reading your PDC file and just reports them as warnings. The default is ON.

Note:
  1. The flow always stops even if this option is deselected in the following two cases:
    • If there is a Tcl error (For example, the command does not exist or the syntax of the command is incorrect)
    • The assign_local_clock command for assigning nets to LocalClocks fails. This may happen if any floor planning DRC check fails, such as, region resource check, fix macro check (one of the load on the net is outside the local clock region). If such an error occurs, then the Compile command fails. Correct your PDC file to proceed.
  2. Every time you invoke this dialog box, this option is reset to its default value ON. This is to ensure that you have a valid PDC file.

Display object names that are no longer found after netlist matching is performed on the design: Displays netlist objects in the PDC that are not found in the imported netlist during the Compile ECO mode. Select this option to report netlist objects not found in the current netlist when reading the internal ECO PDC constraints. The default is OFF.

Limit the number of displayed messages to: Defines the maximum number of errors/warnings to be displayed in the case of reading ECO constraints. The default is 10000 messages.
