Syntax |
cmp find_period <type> <dst id> <dst clk id> <src id> <src clk id> |
Arguments |
<type> |
The description of type. Type max or min for worst case or best case performance of a clock path.
|
<dst id> |
The destination register id. Use empty double quotation marks ("") to return the delay for all destination registers.
|
<dst clk id> |
The destination clock id. Use empty double quotation marks ("") to return the delay for all destination clocks.
|
<src id> |
The source register id. Use empty double quotation marks ("") to return the delay for all source registers.
|
<src clk id> |
The source clock id. Use empty double quotation marks ("") to return the delay for all source clocks.

list of <dst id> <dst clk id> <src id> <src clk id> <delay>ns sorted in descending or ascending order depending on max or min in the following form:
<dst id 1> <dst clk id 1> <src id 1> <src clk id 1> <delay 1> ns { <dst id 2> <dst clk id 2> <src id 2> <src clk id 2> <delay 2> ns} {...} |
TCL_ERROR |
1 |
wrong # args. Usage: cmp find_period type dst_id dst_clk_id src_id src_clk_id |
|
Description |
Finds the maximum or minimum period of clock, register, or register-to-register path(s). You can determine the id number for <dst id>, <dst clk id>, <src id>, and <src clk id> by using the cmp get_timing_nodes function. (Based on the id, you can obtain the node name using the cmp get_timing_node_info function.) |
