LDCP_1 is a transparent data latch with data (D), asynchronous clear (CLR) and preset (PRE) inputs. When CLR is High, it overrides the other inputs and resets the data (Q) output Low. When PRE is High and CLR is Low, it presets the data (Q) output High. Q reflects the data (D) input while gate (G) input, CLR, and PRE are Low. The data on the D input during the Low-to-High gate transition is stored in the latch. The data on the Q output remains unchanged as long as G remains High. The latch is asynchronously cleared, output Low, when power is applied. Virtex2 and Spartan2 simulate power-on when global set/reset (GSR) is active. GSR defaults to active-High but can be inverted by adding an inverter in front of the GSR input of the STARTUP_SPARTAN2 or STARTUP_VIRTEX symbol.

Method Summary | |
boolean |
cellInterfaceDeterminesUniqueNetlistStructure()
When false, the default behavior of this method, each cell will list itself separately in a netlist, guaranteeing that the netlist will not have invalid data at the expense of a larger file-size. |
void |
clock()
Users define synchronous behavior in this method using standard JHDL constructs. |
java.lang.String |
getCellName()
Access the cell name associated with a derived class. |
static void |
main(java.lang.String[] argv)
|
void |
propagate()
Users defined propagatable behavior using standard JHDL constructs. |
void |
reset()
If you define a behavior, you must also define a reset method for resetting the synchonous part of your model. |
static void |
test()
|
int |
type()
This method returns one of the predefined schematic constants to identify the type of this cell. |
