"Violations in the timing constraints of a clocked register can cause a synchronous system to malfunction," scientists in the United States report.
"The effects of parameter variations on the timing characteristics of registers that determine the timing constraints are investigated in this paper," wrote W.R. Roberts and colleagues.
The researchers concluded: "The sensitivity of the setup time and data propagation delay to variations in power supply voltage, temperature, and gate oxide thickness is demonstrated for four different register designs. Furthermore, design modi. cations are proposed that enhance the robustness of each register to variation ...
