Designer Series provides libraries that support the design of ACT 1, the Integrator Series, and the Accelerator Series families of FPGAs. In addition, Designer Series provides ACTmap VHDL Synthesis (a complete VHDL synthesis and logic optimization tool) and ACTgen Macro Builder, which creates complex logic functions to match user-specified parameters. For Cadence, Designer Series supports the following combinations of schematic capture and simulation: Composer and Verilog XL Concept and RapidSIM Concept and Verilog These design flows allow schematics to be created using Composer or Concept. Designer Series products include netlisters that convert Composer or Concept schematics into a netlist format that Designer Series can accept. The netlist is then simulated with unit delays to verify the design functionally before running place and route. After place and route, actual module and net delays are backannotated to the netlist for timing simulation. s DirectTime Analyzer is used to perform static timing analysis on a design identifying critical path delays and performance deltas relative to design specifications. Once the implementation has met all timing requirements, the design can be programmed into an FPGA. s optional DirectTime Layout feature can be added to the basic Designer Series Cadence interface. DirectTime Layout supports specification-driven design. With DirectTime Layout, the system clock frequency or delay constraints for individual signals can be entered. After s standard place-and-route algorithm is executed, the results are shown in the DirectTime Analyzer. DirectTime Analyzer displays a comparison between required versus actual delays. DirectTime Layout can typically improve design performance by an amount equivalent to the next fastest speed grade. It makes performance-runtime trade-offs during placement and routing to achieve the requested timing. 2-18
EDA Vendor Support If the results of standard layout are substantially slower than the required timing, more aggressive measures are needed. The designer has the option of moving to a faster-speed-grade FPGA or even to a faster family. DirectTime Analyzer makes these decisions easy by clearly showing whether the target performance is reached and showing the distance between target and achieved when target is missed. There are many high-level design solutions that support in the Cadence environment. Cadence s Synergy and PIC Designer products as well as Synopsys s Design and FPGA Compilers all work within the Cadence environment. Synthesized blocks in any of these synthesis tools can be combined with schematics to support mixed-level design definition. Cadence provides libraries for the PIC Designer and Synergy synthesis products. s Synopsys synthesis libraries can be added to the Designer Series Development System to support Synopsys synthesis in the Cadence environment. also makes available Verilog and VITAL VHDL libraries so that designs captured in these languages can be simulated directly with Verilog XL or Leapfrog. The Designer Series Development System for Cadence provides a tight link between Cadence s suite of design capture and analysis tools and s FPGA implementation software. The integration of Designer Series with the Cadence tools provides a design environment that delivers high-performance, high-capacity FPGA solutions quickly. Combining the architecture with powerful place-and-route software provides short turnaround time for ECNs. Designer Series makes it easy to include custom logic in any product.

Designer Series for Synopsys EDA Tools Synopsys Verilog HDL/VHDL Synthesis Designer Series Development System ACTgen Pin Editor ChipEdit Compile Layout Standard/DirectTime ACTmap DirectTime Editor DT Analyzer & Back Annotation Activator 2 Activator 2s Data I/O Figure 4 The Synopsys EDA Environment The Synopsys libraries support synthesis of FPGAs from Verilog HDL or VHDL. (See Figure 4.) Support for synthesis, DesignWare, and VHDL System Simulator (VSS) is included. The Synopsys libraries provide a complete top-down design solution. FPGA designs can be compiled with either the Design Compiler or the FPGA Compiler, with the FPGA Compiler yielding more efficient, high-performance FPGA implementations. The combination of s fine-grain, routing-resource-rich architecture and Synopsys s powerful synthesis program delivers high-performance, high-capacity FPGAs. The Synopsys libraries allow designs to be efficiently mapped to the architecture, taking complete advantage of all possible logic module functions. Design implementation efficiency is enhanced by the DesignWare library, which contains -optimized adders, counters, multiplexers, registers, and so on. These logic elements all can be instantiated into a high-level design description. Adders, comparators, and subtracters can be inferred from arithmetic operators that are used in the behavioral description. Synopsys has included -specific optimization, such as sequential mapping, which takes full advantage of the multiplexer-based, flip-flop-oriented FPGA architecture. The combination of Synopsys s optimizations for FPGAs and the optimized DesignWare logic elements generates designs that are typically within 5 percent of what can be achieved by laborious handcrafting. Simulation of the design with its surrounding test bench can be accomplished by using VSS and s VHDL libraries for Synopsys or by using any Verilog simulator and the separately available Verilog libraries. Both the Verilog and VHDL simulation libraries support preroute functional simulation to verify the design s functionality and accurate postroute timing simulation with backannotated (using SDF) actual delays. Timing simulation can be performed with best-case, worst-case, or typical delays to account for variations in voltage, process, and temperature. This accurate timing simulation can identify areas in which timing error is causing a design to malfunction. The Synopsys libraries support many of the FPGA-specific architectural feature, such as ACT 3 s complex I/O cells, 1200XL s wide-decode feature, and 3200DX s quad-clock and embedded RAM features. Synopsys s support of architectural specialties allows designers to maximize FPGA performance 2-24
EDA Vendor Support and usefulness by synthesizing a design that includes high-speed FIFOs or dual-port RAMs in a 32200DX device, or by targeting the I/O flip-flops of the ACT 3 family to locate a high-speed counter right on a data bus. The DesignWare libraries provide a strong advantage in the design of FPGAs. provides a synthetic library in DesignWare, which includes commonly used functions such as accumulators, adders, comparators, counters, decoders, multiplexers, and registers up to 32 bits wide. Each logic function can be created with a designer-selected combination of control signals. By taking advantage of the synthetic library, the VHDL or Verilog code can be fine-tuned for optimal implementation. These libraries are based upon s ACTgen Macro Builder parameterized macro generator, which allows designers to achieve performance comparable to schematic-drawn macros. DesignWare elements can be instantiated into the code or inferred by the compilers, resulting in an extremely efficient design process.
