public class COUNTERS

extends Logic

General Description

The COUNTERS class contains static methods to construct various counters. The methods are wrappers for Logic.Modules.upcnt and Logic.Modules.downcnt. See the links for all the details. The wrappers save the user from dealing with all constructor parameters. They only need to provide the parameters they care about.

Usage Examples:

To use any of these routines you must first import this class:
import byucc.jhdl.Logic.Modules.COUNTERS;

Alternatively, you could import the entire Logic.Modules package:
import byucc.jhdl.Logic.Modules.*;

The first three parameters after this are clr, inc (or dec), and ld. Therefore, the methods are named with that order. If there is only an inc and ld to provide, the method name is IncLd_Upcnt, with parameter order this, inc, ld, ldval, out, name. See the examples below.

Note: When two or more of these signals are asserted at the same time, the order of priority is clr, ld, and then inc.

To instance an upcnt with clear, inc, and load commands, the following method would be used:
COUNTERS.ClrIncLd_UpCnt(this, clear, inc, load, load_data, out, "upcnt_clr_inc_ld");

To instance a clearable downcnt, the method would be:
COUNTERS.Clr_DownCnt(this, clear, out, "downcnt_clr_ld");

For all available methods, see Method Summary or Method Detail.
