DATA SHEET O K I A S I C P R O D U C T S MSM13Q/14Q000 0.35 µm Sea of Gates Arrays November 1999 ■ ■ ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Oki Semiconductor MSM13Q0000/14Q0000 0.35 µm Sea of Gates Arrays DESCRIPTION Oki’s 0.3 5 µm ASIC products deliver ultra-high performance and high density at low power dissipation. The MSM13Q0000/14Q0000 series devices (referred to as “MSM13Q/14Q”) are implemented with the industry-standard Cell-Based Array (CBA) architecture in a Sea-of-Gates (SOG) structure. Built in a 0.35 µm drawn CMOS technology (with an L-Effective of 0.27 µm), these SOG devices are available in three layers (MSM13Q) and four layers (MSM14Q) of metal. The semiconductor process is adapted from Oki’s production-proven 64-Mbit DRAM manufacturing process. The MSM13Q/14Q Series contains 6 arrays each, offering over 1 million raw gates and 352 I/O pads. Up to 66% and 90% of the raw gates can be used for the 3-layer and 4-layer arrays, respectively. Oki’s 0.35 µm family is optimized for 3-V core operation with optimized 3-V I/O buffers and 5-V tolerant 3-V buffers. These SOG products are designed to fit the most popular plastic quad flat packs (QFPs), thin QFPs (TQFPs) , and plastic ball grid array (PBGA) packages. The MSM13Q/14Q Series uses the popular CBA architecture from Silicon Architects of Synopsys which mixes two types of cells (8-transistor compute cells and 4-transistor drive cells) on the same die to deliver high gate density and high drives. The CBA is supported by a rich macro library, optimized for synthesis. Memory blocks are efficiently created by Oki’s memory compilers to generate single- and dual-port RAM’s in high-density and low-power configurations with synchronous RAM options. As such, the MSM13Q/14Q series is well suited to memory-intensive designs with high production volumes approaching the real estate and cost savings of standard cells. At the same time, its SOG architecture allows rapid prototyping turnaround times. Thus, Oki’s MSM13Q/14Q family offers the best of two worlds: quick prototyping of a gate array and low production cost of a standard cell. Oki’s 0.35 µm ASIC products are supported by leading-edge CAD tools including a synthesis-linked floorplanner, motive static timing analyzer, and H-clock tree methodology. They are further supported by specialized macrocells including phase-locked loop (PLL), pseudo-emitter coupled logic (PECL), peripheral component interconnect (PCI), universal synchronous receiver/transmitter (UART) cells, and ARM7TDMI RISC cores.

The arrays also have separate power rings for the internal core functions (VDDC and VSSC) and output drive transistors (VDDO and VSSO). The array architecture uses optimally sized transistors to efficiently implement logic and memory in a metal programmable technology. CBA uses two types of cells: compute cells and drive cells. The compute cell employs four PMOS and four NMOS trasnsistors whose sizes are optimized for logic and memory implementations as shown in Figure 1. The quantity and size of the transistors in a compute cell are carefully selected to maximize the efficiency of most commonly used functions in VLSI design. The drive cell consists of two large PMOS pull-up transistors and two large pull-down transistors. The compute and drive cells are tiled to create a channelless core array, with three comput cells for each drive cell as shown in Figure 2. The 3:1 ratio of compute to drive cells was selected for optimal implementation of emerging applications. Macrocells are created using either compute cells, drive cells, or combinations of compute and drive cells. 2 Oki Semiconductor ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– ■ MSM13Q0000/14Q0000 ■ Compute Cell Compute Cell Compute Cell Drive Cell Figure 1.

Full Scan Path Configuration Floorplanning Design Flow Oki offers three floorplanning tools for high-density ASIC design. The two main purposes for Oki’s floorplanning tool are to: • Ensure conformance of critical circuit performance specifications • Shorten overall design turnaround time (TAT) The supported floorplanners are: Cadence DP3, Gambit GFP, and Oki’s internal floorplanner. In a traditional design approach with synthesis tools, timing violations after prelayout simulation are fixed by manual editing of the netlist. This process is difficult and time consuming. Also, there is no physical cluster information provided in the synthesis tool, and so it is difficult to synthesize logic using predicted interconnection delay due to wire length. Therefore, synthesis tools may create over-optimized results. To minimize these problems, Synopsys proposed a methodology called Links to Layout (LTL). Based on this methodology, Oki developed an interface between Oki’s floorplanners and the Synopsys environment, called Link Synopsys to Floorplanner (LSF). Because not all Synopsys users have access to the Synopsys Floorplan Management tool, Oki developed the LSF system to support both users who can access Oki Semiconductor 11 ■ MSM13Q0000/14Q0000 ■ –––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Synopsys Floorplan Management and users who do not have access to Synopsys Floorplan Management.
