Incrementer Decrementer ParametersParameter Values Defaultdin, dout Port widths (must be > 0) Automaticsign_typeinc_dec_typecout_typeUnsigned, SignedActiveHigh, ActiveLowActiveHigh, ActiveLowUnsignedActiveHighActiveHighDesign Rule Checks• An error is issued if the width of any port cannot be determined or if either of ports cout orinc_dec do not have a fixed width of 1.• A warning is issued and HDL generation fails for this part if any of the ports din, inc_dec ordout are not connected.122<strong>ModuleWare</strong> <strong>Reference</strong> Manual, Library Version 1.9September 18, 2008
Left Shifter (lshift)Arithmetic PartsLeft Shifter (lshift)This part left shifts the input port din by the value given on the input portshift.The result of this shift operation is placed in the output port dout. Theenumerated parameter mode (Logical, Arithmetic, Circular) selects one ofthree shift modes.For logical and arithmetic mode, 0 is shifted in the least significant bit.For circular mode, the most significant bit of the input port din is shiftedinto the least significant bit.This part is equivalent to an n-bit left shifter; where n is the width of the ports din and dout. Theimplementation is controlled via the synthesis script. Silicon compilers perform better with thispart in terms of hardware performance.Functiondout = din
