TimeQuest Collections

The TimeQuest analyzer supports collection application program interfaces (APIs) that provide easy access to ports, pins, cells, or nodes in the design. You can use collection APIs with any valid constraints or tool command language (Tcl) commands specified in the TimeQuest analyzer.

Table 1 describes the collection commands supported by the TimeQuest analyzer.

For more information on collections, refer to the TimeQuest Timing Analyzer chapter or the SDC & TimeQuest API Reference Manual (PDF).
Table 1. Collection Commands

The following example shows various uses of the create_clock and create_generated_clock commands with collection commands.

# Create a simple 10 ns with clock with a 60 % duty cycle
create_clock -period 10 -waveform {0 6} -name clk [get_ports clk]
# The following multicycle applies to all paths ending at registers
# clocked by clk
set_multicycle_path -to [get_clocks clk] 2
