DLATR
Level-sensitive register bank with configurable reset
Description

Parameters
Modelica Standard Library
The DLATR component is a level-sensitive digital register with a high enable and a configurable reset input.
The strength parameter specifies a map on logic signals. Its value consists of a symbol, Sxlh, with xlh being one of the following: X01,X0H,XL1,X0Z,XZ1,WLH,WLZ,WZH,W0H,WL1. The three subscripts define the map:
A U always maps to a U.
{X,Y,W,-} map to the first subscript (x).
{0,L} map to the second subscript (l).
{1,H} map to the third subscript (h).
For example, SX0H means {X,Y,W,-} map to X, {0,L} map to 0, {1,H} map to H.
The ResetMap parameter ia a one-dimensional 9-element array that maps the reset input to the integers 1 to 4, inclusive. The following table defines the output signal levels associated with each integer. Each symbol in a cell corresponds to an output level; the actual output level is determined by the strength parameter map.
