3.5.3 FMF Conversions

The conversions package was contributed to FMF by SEVA Technologies. It is used

in most complex models. It provides functions to perform type conversions

between various signal types (std_logic, std_logic_vector), the numeric type

NATURAL, TIME, and several string types (binary, octal, decimal, and hex). It is well

documented internally.

Table 3.1 shows the various supported conversions along with the name of the

function to use for each conversion.

The primary reason for creating this package was a proliferation of incompati-

ble arithmetic packages provide by simulator vendors. The use of any one of those

packages was likely to ...
