Lengthening Report
In a High Speed environment, the Lengthening Report dialog is displayed when you lengthen multiple signals using the Lengthen command. It provides lengthening information for the signals in a Skew Group, as well as for the pin pairs associated with signals. If all constraints are met that are set in Constraint Browser for the selected signals, then "All constraints met" is displayed in the Report box. If constraints are not met, then relevant columns are displayed in the Report box. These are described below.
Value | Description | |
---|---|---|
Report box | Depending on the constraints specified in Constraint Browser for the selected signals, the tables that are displayed in the Report box contain the following columns. Each column shows constraints information from Constraint Browser, in read-only format. | |
Skew Group | The Skew Group associated with the selected signal. This value is shown in the Skew Group column in the Constraint Browser: Skew Groups Section, Skew tab. | |
Object | The E-Net that you attempt to lengthen. This value is shown in the E-Net column in the Constraint Browser: Skew Groups Section, Skew tab. | |
Pin Pair | The pin pair associated with each E-Net that you attempt to lengthen. This value is shown in the Pin Pair column, in the Constraint Browser: Skew Groups Section, Skew tab. | |
Min | For the relevant Skew Group or signal, the minimum length is shown between the pins in each pin pair. This is specified for a Skew Group or signal in the Pin Pair Length section, in the Constraint Browser: Skew Groups Section, Routing tab. | |
Max | For the relevant Skew Group or signal, the maximum length is shown between the pins in each pin pair. This is specified for a Skew Group or signal in the Pin Pair Length section, in the Constraint Browser: Skew Groups Section, Routing tab. | |
Max Skew | For the relevant Skew Group, this is the maximum difference between the lengths of the pin pairs. | |
Minimum Relative | For the relevant Skew Group, this is the minimum permitted difference between the lengths of the pin pairs and the length of the base signal. | |
Maximum Relative | For the relevant Skew Group, this is the maximum permitted difference between the lengths of the pin pairs and the length of the base signal. | |
Actual Skew | For the relevant Skew Group, this is the difference in length between the lowest and highest pin pair length. | |
Actual Length | The actual length of each pin pair that you attempt to lengthen. This value is shown for the relevant pin pair in the High Speed Routing tab, in the Constraint Browser: Signals section, Signals Tab. | |
Save As | Allows you to save the contents of the lengthening report to a specified location. In the Displayed Save As dialog, select the format of the report in the Save as type box. | |
Allows you to print the contents of the lengthening report to a specified printer. | ||
Close | Closes the Lengthening Report dialog. The Lengthen dialog remains open. |
