Logic PartsInverter (inv)Inverter (inv)This part inverts input port din. The result is placed on the output portdout. Each bit of port dout is the inverse of the corresponding bit of portdin.This part is equivalent to a buffer if either din_type or dout_type are set tobe ActiveLow.Functiondout = NOT(din)Truth TableParametersTable 2-23. Inverter Truth Tabledin(i)dout(i)0 11 0Table 2-24. Inverter ParametersParameter Values Defaultdin, dout Port widths (must be > 0). Automaticdin_type, dout_type ActiveHigh, ActiveLow ActiveHighDesign Rule Checks• An error is issued if the width of any port cannot be determined or if ports din0 and dout arenot the same width.• A warning is issued and HDL generation fails for this part if either of ports din and dout arenot connected.48ModuleWare Reference Manual, Library Version 1.9September 18, 2008
