The SDF file starts with a header section that describes the name of the design the file will back-annotate, the vendor that generated the file, the environment used to generate the timing numbers, and so on After the header, the file consists of a number of cells Each cell in the SDF file represents an instance in the VHDL netlist produced by the place and route tools Each cell contains the type of cell, the instance name in the netlist, and timing information to be back-annotated to the design The VITALcompliant simulator reads the SDF file and matches the generics in the VHDL source with the delay constructs in the SDF file For instance, an IOPATH construct in the SDF file specifies the rising and falling delays from and input to an output signal The IOPATH construct is converted into generic names and values to be applied to the VITAL simulation The designer of the VITAL model must ensure that the names used in the SDF model and the names of the generics used in the VITAL model match so that the generics can be properly matched with proper timing values

The last section is a timing check section that contains timing information for the timing checks of the cell, if they exist The timing check section of the SDF file is read by the VITAL simulator and extracts timing information to plug into generics of the VITAL model The timing check generics control the timing values that are used in the timing checks of the VITAL model while simulation is progressing The cell description in the preceding example is for the DFF model that we looked at earlier There are delay values for CLK to Q, PRN to Q, and CLRN to Q, and values for the setup and hold check

VITAL Simulation
To run the VITAL simulation, the designer first compiles the VITAL library into a simulator library The device manufacturers supply VITAL libraries for their devices Next, the VITAL netlist is compiled to the working library, and, finally, the SDF file is read in to back-annotate the timing data into the design After these steps have been completed, the designer runs the VITAL simulation in the same manner as the RTL simulation that we ran earlier The first step is to compile the VITAL library into a simulator library so that it can be referenced It is best if this library is compiled into the location specified by the netlist from the place and route tool so that no manual code modification is necessary The following shows the first few lines of the VITAL netlist generated by the MaxPlusII place and route tool The complete netlist is on the CD Notice that the VITAL netlist expects the VITAL component declarations, package VCOMPONENTS, to be located in a library named alt_vtl:
-- MAX+plus II Version 72 RC2 2/14/97 -- Sat Oct 25 10:59:34 1997 -LIBRARY IEEE; USE IEEEstd_logic_1164all; LIBRARY alt_vtl; USE alt_vtlVCOMPONENTSall; --ENTITY cpu IS -PORT ( -addr : OUT std_logic_vector(15 downto 0); -data : INOUT std_logic_vector(15 downto 0); -clock : IN std_logic;
