HES-US-1320 Prototyping and Emulation Main Board

fpga boards, fpga board, fpga development board


Aldec’s large capacity board with three XCVU440 logic modules is targeted to high speed physical prototyping and emulation of ASIC and SoC designs. The board provides estimated capacity of 79 Million gates and is easily extendable via backplane and daughter card non-proprietary connectors (BPX & FMC). Each UltraScale FPGA module is connected with DDR4 SO-DIMM to support up to 48 GB aggregated memory. Larger capacity of 316 Million gates can be achieved with four HES-US-1320 boards connected in the backplane board HES7BPX4. Highest I/O count packages of UltraScale devices and proper on-board traces routing assure reliable LVDS and GTH transfers up to the device inherent limits.


Very precisely designed clocking block provides 5 length aligned global clock lines routed to each FPGA device. It also provides multiple configuration options due to integrating different oscillators, programmable clock synthesizers and crosspoint switch multiplexers. The global clock network can be also driven from external sources via dedicated SMA connectors as well as from backplane and daughter card sockets. The global clock network is based on LVDS signalling to assure high level of signals integrity and immunity to distractions. Complementary to global clocks there are separate clock oscillators dedicated to GTH links and DDR memories.

Hosting & Interfaces

The board configuration and monitoring controller is preloaded in a dedicated FPGA (Spartan-6) and provides USB based management interface that is used by Hes.Asic.Proto board configuration and management software available on Linux and Windows host PC. Additional Virtex-7 FPGA can be used as a host bridge with standard interfaces like PCIe x8 Gen3, USB 3.0, QSFP+ and SATA. Ready to use, PCIe host controller is preloaded in Virtex-7 FPGA and the corresponding HES PCIe driver is included. Usage of this host controller is facilitated due to Proto-AXI interface module IP that is based on AMBA AXI standard and accompanying high abstraction level C++ API.

Besides physical prototyping this board can be reused for HES emulation applications like simulation acceleration or co-emulation with virtual models.
