## Compiling the VITAL Library for Use with Leapfrog Software

If you wish to use MAX+PLUS® II-generated Standard Delay Format (SDF) Output Files (.sdo) that contain timing information when performing post-compilation timing simulation with Leapfrog software, you must first compile the VITAL library source files. The VITAL Timing and Primitive package files are located in the $CDS_INST_DIR/tools/leapfrog/files/IEEE.src directory.

To compile the alt_vtl library, follow these steps:

1. Be sure to set up your working environment correctly, as described in Setting Up the MAX+PLUS II/Cadence Working Environment. For example, you must ensure that the appropriate directories are specified in the cds.lib file that is located in your working directory.

2. Create a VHDL design, as described in Creating VHDL Designs for Use with MAX+PLUS II Software and save it in your working directory.

3. Change to the alt_vtl directory by typing `cd /usr/maxplus2/simlib/concept/alt_vtl` at the UNIX prompt.

4. Edit the hdl.var file located in your working directory to include the following line:

   `DEFINE WORK alt_vtl`

5. Create the /usr/maxplus2/simlib/concept/alt_vtl/lib directory.

6. Type the following commands at the UNIX prompt from the /usr/maxplus2/simlib/concept/alt_vtl directory to compile the library: `cv -message -file alt_vtl.vhd`
   `cv -message -file alt_vtl.cmp`
