to_real()

to_real() converts the physical type time value into a real value with respect to the current simulator resolution. The precision of the converted value is determined by the simulator resolution. For example, if you were converting 1900 fs to a real and the simulator resolution was ps, then the real value would be 2.0 (i.e. 2 ps).

Syntax

realval := to_real(timeval); 

Returns

Name	Type	Description
realval	real	The time value represented as a real with respect to the simulator resolution

Arguments

Name	Type	Description
timeval	time	The value of the physical type time

Example

If the simulator resolution is set to ps, and you enter the following function:

realval := to_real(12.99 ns); 

then the value returned to realval would be 12990.0. If you wanted the returned value to be in units of nanoseconds (ns) instead, you would use the get_resolution() function to recalculate the value:

realval := 1e+9 * (to_real(12.99 ns)) * get_resolution(); 

If you wanted the returned value to be in units of femtoseconds (fs), you would enter the function this way:

realval := 1e+15 * (to_real(12.99 ns)) * get_resolution();
