Chapter 3: Tcl Packages & Commands 3–11

advanced_timing

This advanced package contains the set of Tcl functions for traversing the timing netlist and obtaining

information about timing nodes.

The timing netlist is represented using a graph of nodes and edges (the netlist). Nodes can be of type "reg"

(for registers and latches), "pin" (for top-level pins), "clk" (for nodes reported as clocks), "comb" (for all

other combinational nodes), and "keeper" (for registers, latches, top-level pins, and clocks). Edges

represent delays between nodes.

The "get_timing_nodes" command is the main command for access to the timing netlist. Most other

commands are used to obtain information about a node or a path.

This package is available for loading in the following executable:
