File Menu Run Time Upper Bound in 15 Minutes 0 = run until completion (Default setting) Positive integer settings represent 15 minute increments: 1 = 15 minutes 2 = 30 minutes 3 = 45 minutes ... 99 = 24.75 hours This option limits the amount of time the Fitter can spend on partitioning and place/route activities, as follows: Mode 1 The Iterate between parition & place/route option is set to "Y" and the Run Time Upper Bound in 15 minutes option is set to "0." Remaining processing time is (15 * Run Time Upper Bound setting) – (Elapsed time) Mode 2 The Iterate between parition & place/route option is set to "Y" and the Run Time Upper Bound in 15 minutes option is set to a value greater than 0. No time limit is imposed on the Partitioner. A time limit of four hours is imposed on each of the first three place/route iterations. No time limit is imposed on the fourth (final) place/route iteration. Mode 3 The Iterate between parition & place/route option is set to "N." The setting of the Run Time Upper Bound in 15 minutes option is imposed separately on the Partitioner and the Placer/ Router. Maximum total processing time is, therefore, twice the specified time limit: (15 * Run Time Upper Bound setting) for Partitioner (15 * Run Time Upper Bound setting) for Placer/ Router Chapter 4: Menu Reference 82
