Why should Agnisys IDesignSpec be your go-to solution for next-gen SoC design?

Unmatched Feature Set that works for you

When it comes to designing next-gen IPs and SoCs, enterprises need more than just a basic spec tool. While solutions like open source handle basic registers, IDesignSpec delivers the complete toolkit for modern IP/SoC development. It offers a rich array of enterprise-grade features that address the complex needs of modern IP and SoC development. Here’s what sets us apart:

• It handles complex special registers with ease—including counters, interrupt aliases, and other advanced combinations that are essential for today’s sophisticated designs. Competing tools like open source often lack support for these features, giving IDesignSpec a clear and practical advantage.  

• Decoder and Bridge Generation: IDesignSpec automatically generates aggregation logic (decoders) and bridges, thereby reducing the manual effort needed to create interconnected systems and improving design efficiency. By contrast, open source lacks such capability.

• Crossbar Generation: IDesignSpec inherently supports crossbar generation, enabling multiple components within a SoC to communicate efficiently–a feature that enhances scalability and performance. In comparison, tools like open source typically lack native crossbar support, limiting design flexibility for complex systems

• Multiple Bus Domains: IDesignSpec supports multiple bus domains, enabling smooth integration across various bus protocols. This makes it an excellent choice for managing complex SoC architecture with diverse communication needs. In contrast, this capability is also not available in open source

• Low Power RTL Generation: Modern chip designs are often power hungry, but IDesignSpec supports techniques like clock gating right in the RTL output–helping you design more smarter power efficient chips. In contrast open source lacks this support, limiting its usefulness in power-sensitive applications

Superior Customization and Flexibility

• The key strength of IDesignSpec lies in its extensive customization capabilities. With more than 350 configurable properties, organizations can precisely tailor output deliverables to their specific project requirements, offering unmatched flexibility in the industry.
• The dynamic configuration with Tcl/Python API enables users to define configuration settings and properties in Tcl files, allowing on-the-fly modifications

without altering the source specification. This facilitates rapid iteration and adaptation to different design scenarios, thereby saving valuable time and resources.

• IDesignSpec also offers user-defined control signals and diverse software/hardware access types (36 SW and 4 HW) for fine-grained register and interface control—perfect for varied system requirements .

You guessed it right. Yes, none of these features are available in open source!!

Faster Time-to-Market with Efficient Output Generation

• Time is a crucial factor in IP/SoC development, and IDesignSpec stands out by delivering significantly faster HTML output generation compared to competing solutions. This performance boost accelerates design iterations and shortens time-to-market—an essential advantage for enterprises in fast-paced, competitive markets.
• Additionally, IDesignSpec’s seamless Git integration enhances version control, allowing teams to collaborate efficiently and manage changes with ease.

Robust Functional Safety and Verification Features

• Functional safety is a top priority in industries such as automotive, aerospace, and medical devices. IDesignSpec, ISO 26262 certified for automotive, addresses this need with a comprehensive set of safety features, including:
  • Cyclic Redundancy Check (CRC): Ensures data integrity during transmission.
  • Parity/SECDED/Sniffer Bus Parity: Provides robust error detection and correction mechanisms.
  • Rich Set of Checks: Built-in verification checks help identify potential issues early in the design cycle, reducing costly revisions.
• Additionally, IDesignSpec’s UVM RAL (Register Abstraction Layer) support includes coverage, constraint, and callback classes for special registers, enabling thorough verification and validation of designs. This is particularly valuable for enterprises aiming to meet rigorous quality and compliance standards.
