3.1.2 Static Process Compensation
Static process compensation (SPC) follows a similar path to DPTC but without the
temperature compensation aspect. SoCs are designed at the worst-case process corner
(see Figure 3.1 ). However, production wafer lots are typically manufactured close to
a typical point in the “ box ” and as a result can run at a lower voltage and still meet
performance requirements.
SPC is a technique of identifying minimum operating voltage for each SoC at the
production line and programming the fuses with the information. Software reads the fuses ...
