Question

What is a “design corner”? List the design corners that you would test for (a) clock speed; and (b) power consumption

Answer 1

Design corners are the maximum values of a variables which can be provided to a program without breaking it.

It is the value, which tests the limits of a program. It is a upper limit of a value of a variable.

Design corners cannot be dertermined in one go. In a test case the value has to be gradually increased until the system breaks. Also it depends on combnation of other values also to max out the system.

In this case the design corner of a Clock speed, would be the value after which the CPU begins to do transmission delays and the CPU fails to process any more data.

The design corner of power consumtion is the value after which the system fails with internal damages and completely/partially shuts down.

It is critical to find out these values for a PC so that the amnufactures know till how much their PC’s are stable and if they need to improve this numbers. The design corners also depends on other factors like climate, power voltage etc. Manufactures keep this in mind while finding our the design corner and each country may have a separate design corner.
