WireSelection

WireSelection(NameSpace ns)

Method Detail

getStrength

abstract int getStrength(int bitIndex)

Returns the strength and the value for the specified bit of the net, packed as an int (bit << 16 | strength).

getStrengths

abstract void getStrengths(byte[] strengths,
                           int startIndex)

Copies the strengths into the given vector, starting from the given index. Tha last one should be large enough to keep 'em. Mainly used by MContAssignmonitor for port connections.

setStrengths

abstract void setStrengths(byte[] strengths,
                           int startIndex)
                    throws InterpretTimeException

Copies the new assignement strengths, from starting from strengths[startIndex]. Mainly used by MContAssignMonitor for port connections.

release

abstract void release()

Detach this assignement from its taregt wire, so subsequent calls to its compute methid will not

reatach

abstract void reatach()

Re-attaches thie expression to its target wire

breakSelection

abstract void breakSelection(WireSelection[] bits,
                             int startIndex)

Breaks this wire selection into one-bit long ContBitSelects.
