A novel constrained layout placement approach is proposed to enhance the pulse quenching effect in combinational circuits. This constrained algorithm can enlarge the number of quenching cells and shrink the distance between these cells. Simulation results illustrate that the soft error vulnerabilities are effectively reduced by adopting this novel constrained layout placement algorithm with no …
Multiple single-event transients (MSETs) are evaluated from the perspective of sensitive area. First, a simple model is proposed to analyze the sensitive area of simple logic cells. Based on this simple model, the vulnerabilities of MSETs sensitive areas are then calculated. At last, a layout-level approach is designed to reduce the vulnerabilities of the MSETs sensitive areas. Our simulation r…
