[-breakatclk value ] \
[-breakatclr value ]Arguments
-from source_pinSpecifies the name of the source pin for the path.
-to destination_pinSpecifies the name of the destination pin for the path.
-exp valueSpecifies whether to expand the path. The following table shows the acceptable values for this argument:
| Value | Description |
|---|---|
| yes | Expands the path |
| no | Does not expand the path |
-sort valueSpecifies whether to sort the path by either the actual delay or slack value. The following table shows the acceptable values for this argument:
| Value | Description |
|---|---|
| actual | Sorts the path by the actual delay value |
| slack | Sorts the path by the slack value |
-order valueSpecifies whether the maximum list size is based on the longest or shortest paths. The following table shows the acceptable values for this argument:
| Value | Description |
|---|---|
| long | Base the maximum list size on the longest path in the design |
| short | Base the maximum list size on the shortest path in the design |
-case valueSpecifies whether the report will include timing values for the worst, typical, or best cases. The following table shows the acceptable values for this argument:
| Value | Description |
|---|---|
| worst | Includes timing values for the worst cases |
| typ | Includes timing values for typical cases |
| best | Includes timing values for the best cases |
-maxpath maximum_pathsSpecifies the maximum number of paths to display.
-maxexpath maximum_paths_to_expandSpecifies the maximum number of paths to expand.
-mindelay minimum_delaySpecifies the path delay in the minimum delay analysis mode.
-maxdelay maximum_delaySpecifies the path delay in the maximum delay analysis mode.
-breakatclk valueSpecifies whether to break the paths at the register clock pins. The following table shows the acceptable values for this argument:
| Value | Description |
|---|---|
| yes | Breaks the paths at the register clock pins |
| no | Does not break the paths at the register clock pins |
-breakatclr valueSpecifies whether to break the paths at the register clear pins. The following table shows the acceptable values for this argument:
| Value | Description |
|---|---|
| yes | Breaks the paths at the register clear pins |
| no | Does not break the paths at the register clear pins |

Examples
The following example returns the paths from input port headdr_dat<31> to the input pin of register u0_headdr_datal_reg/data_out_t_31 under typical conditions.
timer get path from "headdr_dat<31>" \
-to "u0_headdr_datal_reg/data_out_t_31/UO:D" \
-case typ \
-exp "yes" \
-maxpath "100" \
-maxexpapth "10"
The following example returns the paths from the clock pin of register gearbox_inst/bits64_out_reg<55> to the output port pma_tx_data_64bit[55]
timer_get_path from "gearbox_inst/bits64_out_reg<55>/UO:CLK" \
-to {pma_tx_data_64bit [55]} \
-exp "yes"
