Highly Configurable FinFET-Class 7nm Networking IP Platform

New Architectures Deliver Unprecedented Performance, Density and Configurability

eSilicon offers a set of high-performance and high-bandwidth IP and 2.5D solutions on 7nm technology that target networking and data center applications by offering 56G/112G SerDes, fast caches with more than a 35% increase in performance and TCAMs offering more than a 50% increase in performance from previous FinFET generations, along with the 2.5D integration of up to 1228Gbytes/sec data rate high-bandwidth memory (HBM2).

7nm High-Bandwidth Networking & High-Performance Computing IP Platform

The 7nm IP platform is eSilicon’s second-generation platform, with architectural enhancements from our silicon-proven platform in previous FinFET technologies. It was designed specifically to meet the high-speed and high-bandwidth requirements of ASICs and ASSPs targeted for networking and data center applications.

eSilicon’s 7nm IP platform delivers a complete ecosystem of networking-optimized IP with high configurability designed in. All IP in the platform is “plug and play,” using the same metal stack, reliability requirements, operating ranges, control interfaces and DFT methodology. This configurability and compatibility results in better performance, higher density and faster time to market.

The platform includes the following IP:

• 56G/112G long-reach SerDes
• High-speed single-port ternary CAM (SP TCAM) compiler
• High-speed single-port fast cache (FC) compiler
• High-speed single-port (SP) SRAM compiler
• High-speed dual-port (DP) SRAM compiler
• High-speed 2-port asynchronous register file (2PARF) compiler
• High-speed pseudo 2-port (P2P) SRAM compiler
• Ultra-high-density (UHD) pseudo 2-port (P2P) SRAM compiler
• High-speed pseudo 4-port (P4P) SRAM compiler
• High-speed pseudo quad-port (PQP) SRAM compiler
• 1024 bit HBM2 PHY
• 1.8V oxide 1.8V LVDS I/O library
• 1.8V oxide 1.8V/2.5V/3.3V general-purpose I/O library

Highlights of the New Architectures

Optimized for Performance

• Except for the UHD P2P SRAM, all memory compilers in the 7nm IP platform are optimized for performance, offering a greater than 35% increase in performance from previous FinFET generations
• High-speed fast cache compiler offers extreme speeds suitable for compute-intensive applications
• High-speed P2P SRAM compiler is expected to run at increased performance while providing high density for two-port functionality

Optimized for Bandwidth, Density & Power

• The high-speed pseudo four-port and pseudo quad-port SRAM are new architectures introduced in 7nm to support parallel operations to increase system bandwidth. The PQP allows up to four simultaneous read or write operations. The P4P and PQP provide high bandwidth with the best density and power savings for critical applications requiring multi-port architectures.
• For applications requiring lower clock speeds, the ultra-high-density pseudo two-port SRAM compiler provides extreme area savings and reduction in dynamic and leakage power by up to 40 and 70 percent, respectively.

56G/112G 7nm SerDes

At the core of the platform is eSilicon’s SerDes technology, a new breed of performance and versatility based on a novel DSP-based architecture. Two 7nm PHYs support 56G and 112G NRZ/PAM4 operation to provide the best power efficiency tradeoffs for server, fabric and line-card applications. The architecture delivers unprecedented power efficiency for a true long-reach capability, with hole-free operation down to 1 Gb/s. The clocking architecture provides extreme flexibility to support multi-link and multi-rate operations per SerDes lane. A multitude of protocols are supported including Ethernet and Fibre Channel. The architecture allows scaling power consumption even further for shorter-reach channels.

Why TCAM?

Memory processing tends to be the bottleneck in network performance. If memory can’t keep up with increasingly fast processors, the processors have to wait, stalling the system. Specialty memories address the problem in a variety of ways. Ternary content-addressable memories (TCAMs) are unique: they search an entire lookup table in one cycle. eSilicon’s ternary CAM compiler offers more than a 50% increase in performance, compared to previous FinFET generations, enabling high-efficiency, cost-effective solutions for applications such as network search engines, cache for network processors, QoS services, classifications, Ethernet, ATM switches and other diverse networking applications.

TCAM Standard Features

• Flexible selection of width and depth with up to 1K entries and 160Kb macro size
• Hand-crafted layout for high density and performance
• Easily cascadable to increase search depth without degradation in performance
• Single-cycle search, read and write operations
• Smart Power Management
• Fast cycle and access time: the 7nm TCAM offers more than a 50% increase in performance
• Valid bit, global and local valid-bit reset
• Match-in and match-out flag for each entry
• Partial pipelined search option for reduced power
• Flexible masking (bit/group/global)

User-selectable features include priority encoder, redundancy and bit-write options.

Patented Duo architecture may be licensed for reduced area and power savings for bit widths less than or equal to 80 bits.

High-Bandwidth Memory

High-bandwidth memory (HBM2) achieves higher bandwidth while consuming less power in a substantially smaller form factor than DDR4, or GDDR5. HBM2 technology addresses the bandwidth gap with up to 1228 Gbytes/sec data rate with four HBM2 stacks in a package. HBM2 has eight independent channels using a total of 1024 input and output pins. This density of signals, coupled with interposer design, requires careful design and thorough timing analysis. eSilicon has extensive experience in HBM2 systems, including IP design, systems in package (SiP) design, manufacturing, assembly and test.

HBM2 PHY

The HBM2 PHY supports HBM2 based on the JEDEC JESD 235A standard. The PHY supports up to 307Gbytes/sec bandwidth with 8x128b channels at 2.4Gbps per I/O. The PHY is DFI 4.0 compliant with several controller-independent features such as:

• Plug & play: with hard macro and built-in clock control there’s no lengthy timing closure and physical design
• Optimized timing and area
• Rich set of built-in features
• Flexible: minimum dependence on controller features
• Signal integrity: proprietary routing scheme used on interposer to significantly minimize crosstalk and skew
• Maximum timing margin: PHY includes training, calibration and VREF programmability features
• DFI and IEEE1500 compliant
• APB interface enables CPU override of built-in training, repair and calibration
