For LVDS receivers, the Quartus II software provides an RSKM report showing the
SW, TUI, and RSKM values for non-DPA mode. You can generate the RSKM report by
executing the report_RSKM command in the TimeQuest Timing Analyzer. You can find
the RSKM report in the Quartus II compilation report under the TimeQuest Timing
Analyzer section.
1 In order to obtain the RSKM value, you must assign an appropriate input delay to the
LVDS receiver through the TimeQuest Timing Analyzer constraints menu.
For assigning input delay, follow these steps:
1. The Quartus II TimeQuest Timing Analyzer GUI has many options for setting the
constraints and analyzing the design. Figure 8–28 shows various commands on
the Constraints menu. For setting input delay, you must select the Set Input Delay
option.
