Latch-up has long been the cause of grief and frustration for circuit designers. While mitigation solutions exist, they are typically applied after layout, when changes are difficult and time-consuming. Performing topological analysis on the schematic netlist quickly identifies latch-up sensitive scenarios. Designers can then take proactive action during layout to avoid or minimize the creation of susceptible configurations. Finding and preventing latch-up conditions earlier in the design flow not only helps prevent costly design changes late in the schedule, but also contributes to higher product reliability.
