Summary: Realistic semiconductor IC project planning hinges on industry-norm effort, which is the comparison of the actual productivity achieved by teams across the industry and the actual complexity of their designs.

Complexity is a measurement of how difficult it is to complete a design. It’s a measurement based on many attributes of the design, carefully correlated across multiple historical designs. But in order to plan, we need to know the amount of effort it will take to complete a design of a certain complexity. The answer lies in a comparison of the actual productivity achieved by teams across the industry and the actual complexity of their designs.

From this comparison we can calculate the amount of complexity an average designer can implement in a unit of time. Because this is a normative value calculated across the industry, we call it industry norm effort.

We can also make the same calculation for your company—assessing the amount of complexity your designers have historically been able to implement in a unit time. By comparing this with the industry norm, you will get a sense of how your team is doing as compared with the industry.

But the main use of industry norm effort is in conjunction with the complexity data for a proposed design:

• We can accurately and rapidly calculate the total effort required for that design using either your company data, or the industry norm data.

This provides a firm foundation for realistic planning, while still allowing you to set aggressive (but not unrealistic) targets for your team.

Summary: Design complexity can be quantified and communicated in a way that makes IC projects predictable and more productive.

It doesn’t take a rocket scientist to know that the resources and time required to build a chip vary from one design to another. The variation is a function of how difficult the chip will be to build. We measure that and call it complexity.

The hard part, however, is to know which attributes of the design correlate to the effort required to build the chip.

• Is clock speed important?
• What about the number of transistors?
• Re-use?
• Analog and mixed signal?
• Voltage islands?
• Modes?

The list goes on and on. One of the reasons why the NMX-ERP™ software suite accurately forecasts the time and resource requirements for a design is that our engineers, using more than a thousand design projects, have developed a deep understanding of just how hard a given project may be so your engineers can be more productive.

Knowing how to translate chip-design attributes into complexity is the foundation of apples-to-apples comparisons between designs. That’s critical to making sure your latest design can be compared with other industry designs, as well as designs your company has done in the past. After taking in all the complexity factors as chip specifications, Numetrics’ engines can reliably and rapidly calculate the relative complexity of your design, as compared with every other design in our industry database. That’s the foundation upon which all the plan synthesis, what-if scenario analysis, re-planning and root-cause analysis capabilities of NMX-ERP are built.
