Enabling an HBM controller adds the HBM Configuration tab. The following figure shows the HBM Configuration tab.
Figure 1. HBM Configuration Tab
- Configure all Channels to Same Value?
- Select Yes to configure all memory controllers to use the same settings. Select No to configure memory controller options independently.
- HBM Clock
- Select between internal clock (HSM0) or the external clock pins for the HBM. If the external clock source is selected, you need to select the IO standard for the reference clock. The supported IO standards are LVDS for differential clock and LVCMOS for Single-ended clock.
- HBM Memory Frequency for Stack
- Select the operating frequency of the HBM. HBM operates in Double data rate mode and hence the actual data rate is double the frequency set in this option.
- HBM Reference Frequency for Stack
- Select the frequency provided to the reference clock port. Internal clock has a range of 100-200 MHz and the external clock has a range of 100-500 MHz.
- Configure Channels
- Clicking this button launches a Configure Channels dialog box. The new dialog box has
the following three tabs:
- HBM Address Map Options
- HBM Refresh and Power Savings Options
- HBM Reliability Options
