Enumeration Type Documentation

enum lcs::ExprType

An enumeration enumerating types for the various kinds of operations which can be used in an expression. The expression should consist of operands of type lcs::InputBus (and hence, can be of type lcs::Bus) or lcs::BitBuffer, or bit-selects of busses or bit buffers.

Enumerator:
BUS_EXPR  Indicates an expression which consists of a single bus.
BITWISE_AND_EXPR  Indicates an expression which is a bitwise AND operation.
BITWISE_OR_EXPR  Indicates an expression which is a bitwise OR operation.
BITWISE_XOR_EXPR  Indicates an expression which is a bitwise XOR operation.
ONES_COMPLEMENT_EXPR  Indicates an expression which is a one's complement operation.
BITBUFF_EXPR  Indicates an expression which consists of a single bit buffer.

enum lcs::LineState

An enumerated set of data types which denote the state of a data line. A line can have four possible states: LOW, HIGH, UNKNOWN, HIGH_IMPEDENCE. Each of these states denote a single bit value.Click on each state to know more about them.

Enumerator:
LOW  A state which denotes a logic level of 0. It is displayed on the screen as the character '0'.
HIGH  A state which denotes a logic level of 1. It is displayed on the screen as the character '1'.
UNKNOWN  A state which denotes an unknown logic level. It is displayed on the screen as the character 'x'.
HIGH_IMPEDENCE  A state which denotes a high imepedence line. It is displayed on the screen as the character 'z'.

enum lcs::LineEvent

An enumeration to define possible of lines events. A line event occurs when the state of a line changes. A line event can occur in three different ways: 1. When the line state changes, 2. When the state of the line is changing from lcs::LOW to lcs::HIGH, and 3. When the state of the line is changing from lcs::HIGH to lcs::LOW.

Enumerator:
LINE_STATE_CHANGE  The value which denotes a line state change event.
LINE_POS_EDGE  The value which denotes positive edge event, or the event of the line state changing from lcs::LOW to lcs::HIGH event.
LINE_NEG_EDGE  The value which denotes negetive edge event, or the event of the line state changing from lcs::HIGH to lcs::LOW event.

enum lcs::PulseEdge

An enumeration to define the two possible edge types of pulse signals.

Enumerator:
POS_EDGE  The value which denotes a positive edge of a pulse signal.
NEG_EDGE  The value which denotes a negetive edge of a pulse signal.

enum lcs::SortOrder

An enumerated type which enumerates the various possible sorting orders.

Enumerator:
ASCENDING  Indicates an ascending order.
DESCENDING  Indicates a descending order.

enum lcs::TimeUnit

An enumeration which specifies types for the unit which can be associated with the system time.

Enumerator:
FEMTO_SECOND  Indicates a femto second.
PICO_SECOND  Indicates a pico second.
NANO_SECOND  Indicates a nano second.
MICRO_SECOND  Indicates a micro second.
MILLI_SECOND  Indicates a milli second.
SECOND  Indicates a second.

enum lcs::DumpOption

An enumerated set of options which indicate if changes in the values of a variable should be dumped into a VCD file or not.

Enumerator:
DUMP_OFF  Indicates that the variable values should not be dumped into a VCD file.
DUMP_ON  Indicates that the variable values should be dumped into a VCD file.
