TMC-20217: Paths Failing Setup Analysis with Clock-As-Data
Description
Violations of this rule indicate setup-failing timing paths that use the same signal as both From Node and Launch Clock.
Parameters
| Name | Description | Type | Default Value | Min Value | Max Value |
|---|---|---|---|---|---|
| maximum_setup_slack | Reports a violation for timing paths that have a setup slack below the value of this parameter. | double | 0.0 | ||
| to_clock_filter | Reports a violation for timing paths that end at a register in a clock domain that matches the value of this parameter. | string | * | ||
| minimum_number_of_adders | Reports a violation for timing endpoints that are preceded by a number of independent adder chains greater than or equal to this value. | integer | 3 | ||
| minimum_number_of_soft_mult_chains | Reports a violation for timing endpoints that are preceded by a number of independent adder chains that are implementing multiplier logic greater than or equal to this value. | integer | 2 |
Recommendation
Restructure or reconstrain the path to capture the data safely.
