LogiBlox Functions
The following LogiBLOX modules can be used in schematics
Module |
Description |
ACCUMULATOR |
Adds data to or subtracts it from
the current value stored in the accumulator register |
ADDER/SUBTRACTOR |
Adds or subtracts two data inputs
and a carry input |
CLOCK DIVIDER |
Generates a clock pulse whose
period is a multiple of the clock input period |
COMPARATOR |
Compares the magnitude or equality
of two values |
CONSTANT |
Forces a constant value onto a bus |
COUNTER |
Generates a sequence of count values |
DATA REGISTER |
Captures the input data on active
CLOCK transitions |
DECODER |
Routes input data of 1-of-n lines
on the output port |
INPUT/OUTPUT |
Connects internal and external pin signals |
MULTIPLEXER |
Type 1, Type 2 - Routes input
data on 1-of-n lines to the output port |
PAD |
Simulates an input/output pad |
SHIFT REGISTER |
Shifts the input data to the left
or right |
SIMPLE GATES |
Type 1, Type 2, Type 3 -;
Implements the AND, INVERT, NAND, NOR, OR, XNOR, and XOR logic functions |
TRISTATE BUFFER |
Creates a tristate internal data
bus. Not available on XC9500XL devices |
