1 Open Verification Session Interoperability Developers Forum Kevin Kranen Director, Strategic Programs Strategic Market Development Synopsys, Inc. October 16, 2003

2 Open Verification Agenda Introduction Leveraging OpenVera into SystemVerilog, Sashi Obilisetty, VeriEZ Solutions SystemVerilog: A Synthesis Perspective, Karen Pieper, Synopsys EDA & SystemVerilog, Dennis Brophy, MTI EDA & SystemVerilog, Steve Wang, Axis Systems Assertions Update for SystemVerilog, Bruce Greene, Synopsys

Pieper, Synopsys EDA & SystemVerilog, Dennis Brophy, MTI EDA & SystemVerilog,

3 Two things to remember: Full Speed ahead with SystemVerilog! You are safe and secure with your other previous standards investments!

4 Synopsys Delivering SystemVerilog to Designers Today! SystemVerilog is THE HDVL Hardware Definition and Verification Language Synopsys Products support SystemVerilog VCS, HDL Compiler. Design Compiler, Leda Formality and additional products coming soon Accelerated assertion support driven by market needs SystemVerilog Catalyst Over 40 companies Enabling all EDA and IP providers to adopt faster SystemVerilog NOW! Market Education Sponsored by 5 EDA Verification Leaders Over 1,000 user registered to attend

5 Language Fragmentation Has Led to Pain Assertion Language Assertion Engine Auto Testbench HVL Property C/C++ Simulation Reference Models Coverage C/C++ Verilog, VHDL Painful for design and verification engineers HDL English Spec *!$&*!! Painful for EDA and IP developers HVL

Coverage C/C++ Verilog, VHDL Painful for design and verification

6 RTL Verification Today Specification HDLs: Verilog, VHDL Design HDLs, HVL, C++ Home Grown, etc Verification Verification Environment Multiple point tools Inefficient tool interaction Multiple Intent definitions and coverage metrics

Verification Environment Multiple point tools Inefficient

7 Unified Design & Verification Methodology Specification Design HDL HVL Verification DUT Unified Design and Verification

8 SystemVerilog: Everything needed for Design and Verification SystemVerilog for Verification Automated Testbench Assertions SystemVerilog for Design Communication Interfaces Advanced Verilog Verilog 2001 Verilog 95 Concise Design Features Comprehensive APIs Datatypes (C) Single language for design, assertions and testbench Supports increase code conciseness Evolves Verilog into a HDVL SystemVerilog 100% compatible with Verilog

Verilog 95 Concise Design Features Comprehensive APIs Datatypes (C) Single language for design, assertions

9 SystemVerilog Means Productivity Netlist RTL SystemVerilog RTL Designer Productivity Comprehensive Verification Env. Simulation Coverage Formal Property Assertions Testbench HDL Simulation Co-Sim Overhead Testbench Hardware-assisted verification Enhanced Verification SystemVerilog Verification Speed

Simulation Coverage Formal Property Assertions Testbench HDL Simulation

10 Increasing Designer Productivity Netlist RTL SystemVerilog RTL Designer Productivity 2X 5X less code to capture the same functionality Less code Fewer bugs Easier to interpret and communicate among teams Evolutionary: Reduces learning curve

same functionality Less code Fewer bugs Easier to interpret

11 Examples of Concise Coding Constructs Structures and user defined data types Improves data modeling, simplifies port lists Interfaces Define once, use many times Encapsulates communication between modules Can be designed/verified separately Supports multiple levels of abstraction signal level, transaction Less code still synthesizable

times Encapsulates communication between modules Can be designed/verified

12 Other Improvements To Benefit Designers Strong type checking Global type system earlier detection of errors Many language improvements Same semantics interpretation by all tools Enhanced programming statements and operators Enhanced tasks and functions Eliminate simulation and synthesis mismatches 2-state types reduces overall memory requirements always_comb, always_latch, always_ff

Enhanced programming statements and operators Enhanced tasks and functions Eliminate simulation

13 SystemVerilog Enables Greater Verification Speed HDL Simulation Co-Sim Overhead Testbench SystemVerilog Verification Speed Unified language for design and verification improves effectiveness Advanced constrained-random test generation Fully integrated, complete assertion technology Easy integration of C Models

design and verification improves effectiveness Advanced constrained-random

14 Benefits of Single Language for Design AND Testbench Easy learning curve Facilitates quicker adoption Improved communication between design and verification teams Reduces design and verification complexity with advanced constructs Enables faster tools and acceleration

design and verification teams Reduces design and verification

15 SystemVerilog Powers Comprehensive Comprehensive Verification Env. Verification Simulation Coverage Assertions Formal Property Testbench Hardware-assisted verification Enhanced Verification Integrated assertions expand effectiveness of verification methodology Assertion-based verification Formal property verification Across the board verification acceleration
