Finding CDC Issues Before They Find You: Advanced CDC Verification for DO-254 Compliance   
Clock domain crossings (CDCs) in FPGAs represent a probabilistic opportunity for failure. Functional simulation and static timing analysis tools are insufficient. Finding and addressing metastability and data incoherence around CDCs require static and dynamic analysis of FPGA designs. Aldec ALINT-PRO-CDC provides enhanced confidence that CDCs are located and fully mitigated.

HDL Simulation And Mathematical Modeling Integration   
Abstract: This paper presents a new approach in domain of high level digital circuits simulation and modeling that benefits from high level mathematical environment delivered by MATLAB. It allows to integrate design process and directly verify obtained results with mathematical formulas or complex operations that are not available in standard HDL languages. A part of HDL code can be placed for verification purposes inside the advanced mathematical model or can execute complex calculation. Paper presents problems that are introduced by hybrid simulation and modeling environment concerning data representation, simulation process and optimal performance.

Interoperable IP Delivery   
Abstract: This paper describes the theoretical background, current status and future challenges facing interoperable cryptosystem for safe delivery of Intellectual Property (IP) to be used in VHDL and SystemVerilog design and verification. The system must be reliable, and interoperable, i.e. enable safe use of IP source in a variety of tools. IEEE P1735 Working Group currently develops proposed standard describing such a cryptosystem.

Introducing Transactions In Design Verification   
Abstract: Modern ASIC and FPGA designs can usually be treated as complete systems, not just electronic circuits. Design and verification of those systems typically requires the use of transaction-level descriptions, so enhanced support for transactions in verification tools is critical. This paper describes basic transaction related terms and the new transaction recording and visualization solution available in Riviera-PRO™ simulator.

Making Floating-Point Arithmetic Work in Your RTL Design   
Floating-point arithmetic becomes a widely used format in digital system design. For example, DSP applications often demand high precision while operating with large dynamic ranges. The IEEE 754™-2008 floating-point arithmetic standard fulfills this criterion but it might be extremely hard to comprehend and use. This document discusses challenges associated with debugging floating-point arithmetic designs and explains how to tackle them using the tools available with your floating-point aware IDE.

Managing Validation and Verification Activities for DO-254   
This paper provides an overview of the Validation and Verification (V & V) process and its associated activities as described in RTCA/DO-254. With the growing size and complexity of today’s FPGAs, managing V & V activities is becoming difficult and time-consuming. This paper presents a list of recommended features, methodologies and capabilities that must be supported by a tool to manage V & V activities more efficiently.

SCE-MI Macro-Based Interface for System-on-Chip Verification   
As System-on-Chip (SoC) designs grow more complex they demand a higher-level of abstraction to functionally verify all modes of operation. The main focus of Accelera’s SCE-MI Co-Emulation Modeling Interface is to avoid communication bottlenecks when interfacing software models to current hardware emulation platforms during SoC verification. This allows the system to be modeled realizing its full performance potential. In this white paper, we will be discussing the Macro-based SCE-MI interface which utilizes synthesizable RTL macros which provide connection points between transactors and SCE-MI infrastructure.

Simulation Acceleration with HES XCELL   
Abstract: Comprehensive verification that can be provided by HDL simulators is good, but not ideal. What is necessary is a faster, safer and more thorough verification environment that combines the robustness of an HDL simulator with the speed of FPGA prototyping boards. The goal is to put together the power of these two verification methodologies into one platform.

SoC verification made easy with Aldec HES-DVM   
As designs grow larger, the time spent verifying a project is growing longer as well. As a solution, some companies are trying to ‘shift-left’ their schedules. Verification via software simulators is not fast enough for large System-on-Chip (SoC) design projects, therefore one option is to use an FPGA emulator to speed up the design process. But what happens when a bug occurs? This document describes Aldec® HES-DVM™ features that can help speed up debug and verification of the SoC, in order to achieve faster time-to-market.
