2.6.4.2. Viewing Reset Domains in a System

On the Reset Domains tab, you can filter the System View tab to display a single reset domain, or multiple reset domains. When you select an element in the Reset Domains tab, the corresponding selection appears in the System View tab.
Follow these steps to filter and highlight reset domains in the System View :
  1. To open the Reset Domains tab, click View > Reset Domains.
  2. To show reset domains in the System View tab, click the Show reset domains in the system table icon in the System View tab.
    Figure 27. Show Reset Domains in the System Table
  3. To view a single reset domain, or multiple reset domains and their modules and connections, click the reset names in the Reset Domain tab.
    Figure 28. Selected Reset Signal in Reset Domains and System View Tabs
    Platform Designer displays your selection according to the following rules:
    • When you select multiple reset domains, the System View tab shows interfaces and modules in both reset domains.
    • When you select a single reset domain, the other reset domains are grayed out, unless the two domains have interfaces in common.
    • Reset interfaces appear black when connected to multiple reset domains.
    • Reset interfaces appear gray when they are not connected to all of the selected reset domains.
    • If an interface is contained in multiple reset domains, the interface is grayed out.

    Detailed information for your selection appears in the reset domain details pane. Red dots in the Connections column between reset sinks and sources indicate auto insertions by Platform Designer during system generation, for example, a reset synchronizer. Platform Designer decides when to display a red dot with the following protocol, and ends the decision process at first match.

    • Multiple resets fan into a common sink.
    • Reset inputs are associated with different clock domains.
    • Reset inputs have different synchronicity.
