Quality intellectual property metric

What is QIP Metric?

QIP (Quality Intellectual Property) Metric is a standard, developed by Virtual Socket Interface Alliance (VSIA) for measuring IP or SIP (Silicon intellectual property) quality and examining the practices used to design, integrate and support the SIP. SIP hardening is required to facilitate the reuse of IP in IC design.

Background and Importance

Application is driving the need for higher complexity and performance IP-based System-on-a-chip (SoC) design. One solution is the reuse of high quality IP. IP quality is the key to successful SoC designs, but it is one of the SoC’s most challenging problems.

• QIP Metric allows both the IP designers and IP integrators to measure the quality of an IP core against a checklist of critical issues.
• IP integrators make use of the IP cores into their own design and deliver final IC circuit for an application, e.g. a IC circuit designer of iPhone main processor IC (ARM_architecture CPU) integrates other IP cores like USB 2.0, DSP, MP4 decoder, etc., so that the additional features of USB 2.0, MP4 decoder, etc can be easily embedded into the final IC.
  
• The QIP consists of interactive Microsoft Excel™ spreadsheets with sets of questions to be answered by the IP vendor.

SIP Quality Measure Framework

Hong Kong Science and Technology Parks Corporation (HKSTP, which was set up by Hong Kong government) and Hong Kong University of Science and Technology (HKUST) started to develop a SIP verification and quality measures framework in 2005, based on QIP metric. The objective is to develop a technical framework for SIP quality measures and evaluation based on QIP. Third-party SIP evaluation service is provided by HKSTP, so that IP integrators can know the quality of their desired SIP cores.

Soft and Hard SIP

There are soft SIP and hard SIP verification and quality measures.

• Soft IP comes with design source code in the form of synthesizable HDL (Hardware description language) code (VHDL and Verilog are HDL).
• Hard IP is a design macro and model without HDL code available; they are optimized for power, size or performance, and mapped to a specific Process technology. Also refer to SIP hardening.
