Not only can objects be aliased in VHDL93 but functions can as well To specify a function alias requires a subprogram signature specification The signature specifies the types of the input parameters as well as the type of the return parameter An example is shown here:

`ASCENDING In VHDL87 it was tedious to find if a particular range was ascending or descending The `high and `low attributes of the type had to be compared to determine if the range was truly ascending, a null range, or a single value Attribute `ascending will return true if the range is ascending or false if not An example is shown here:

`DRIVING_VALUE In VHDL87 the value of an output port could not be read To do this required the port mode of the port to be inout, or the use of an internal signal These workarounds caused an increase in complexity that typically was not warranted and therefore to get around this inconvenience VHDL93 adds attribute `driving_value Attribute `driving_value allows the ability to read the value component of

the resolved value that a particular driver is driving so that it can be further used in the model In the example shown here the second component instantiation statement would cause an error because input port a of U2 is trying to read the current value of dout In VHDL93 the `driving_value attribute gets around this problem by reading the driving value of dout
ENTITY invert IS PORT( w: IN STD_LOGIC; dout, doutb : OUT STD_LOGIC); END invert; ARCHITECTURE struct OF invert IS COMPONENT inv PORT( a : IN STD_LOGIC; q : OUT STD_LOGIC); END COMPONENT; BEGIN u1 : inv PORT MAP(a => w, q => dout); --u2 : inv PORT MAP(a => dout, q => doutb); -- won t work because port -- dout cannot be read u2 : inv PORT MAP(a => dout`DRIVING_VALUE, q => doutb); -- In VHDL93 this -- will work END struct;
`IMAGE AND `VALUE In VHDL87 it was difficult for an error message to display the actual error value of a signal or a variable in a string In VHDL93 the attributes `IMAGE and `VALUE allow the modeler to convert to and from type values into string values Attribute `IMAGE converts a type value into a string, and attribute `VALUE converts a string to a type value `PATHNAME, `INSTANCE_NAME, AND `SIMPLE_NAME The other difficulty in VHDL87 of model error reporting was to uniquely determine exactly which instance of a model was generating a message Most VHDL simulators had some mechanism of reporting the instance information to the modeler, but this information was simulator-specific and not standard In VHDL93 three new attributes allow the modeler access to all parts of the pathname that describes which instance a particular message is generated from I `SIMPLE_NAME returns a string which is the local name of the calling entity I `PATH_NAME returns a string that describes the path to the entity starting at the root of the design The `PATH_NAME attribute does not include the names of instantiated entities (`INSTANCE_NAME does)
Appendix D: VHDL93 Updates
I `INSTANCE_NAME returns a string that describes the path to the entity starting at the root of the design The `INSTANCE_NAME attribute also includes the names of instantiated entities These entities are specified using a label@entity(architecture) syntax
