The Multi Rate GTM Wizard is an advanced option that you can select in GTM Wizard IP (Basic Tab). These extensions include updates to the GTM Controller logic, to support the rate change feature on top of the existing Sampled Eye Scan functionality and other existing features. The rate change function retrieves the DRP register values, port settings and default value updates from the rate table, and apply the same on to the GTM wizard. The existing support of up to four duals per IP remains the same. The management of user facing rate change interface is provided at the example design level. In conjunction with the existing GTM helper modules, the GTM reset sequencing post rate change is managed by the internal logic, conditionally depending on the port tie off values as described below.
