Multicontroller Design

Introduction

This chapter describes the specifications (including the supported features and
unsupported features) and pinout rules for multicontroller designs.
The supported and unsupported features are:
• Supports up to eight controllers
Multi-interface support includes the combination of all memory interfaces as DDR3
°
SDRAM (Native only), QDR II+ SRAM, and RLDRAM II up to total of eight
controllers. Multi-interface support with the DDR3 SDRAM AXI interface combined
with other memory interfaces is not supported.
Multicontroller for DDR3 SDRAM (AXI only) interface is supported up to eight
°
independent controllers. Multicontroller support combining DDR3 SDRAM Native
and AXI interface designs is not supported.
• Banks selected for one of the controllers are not allowed for other controllers; that is,
across the same memory interfaces and different memory interfaces.
• Memory options (frequency, data width, etc.) and all other options remain the same as
for single controller options.
• Sharing of banks across two different controllers is not allowed.
• Rules for all memory interfaces (DDR3 SDRAM, QDR II+ SRAM, and RLDRAM II) remain
the same as for single controller designs.
Memory Interface Solutions v4.1 only supports the Vivado
IMPORTANT:
Design Suite is not supported in this version.
