XPLA Designer v2.1 User's Manual

PZ5000 series devices use a 5-volt supply. The number of macrocells is the last 3 digits inthe 3000/5000 number. The speed grade is generally related to the pin to pin delay, and isdesignated next, followed by the package definition. This design targets an 8 ns PZ3032 ina 44-pin PLCC. Select the PZ3032-8-PLCC44.Figure 12Compile the DesignPrior to compilation and fitting, select the compilation options. As seen in Figure 12,compilation options can be selected from the main interface screen via pull-down menuoptions and check boxes. The PZ3000/PZ5000 series can support from 5 to 37 P-terms/macrocell. There is an incremental pin to pin delay for macrocells in which thenumber of P-terms exceeds 5. Using the pull-down menu next to MAX P-Terms perequation, change the maximum P-term per equation to 5. The user can define pinassignments in the phdl file. As a compilation option, the user can define the level ofeffort that the fitter should use to maintain the pinout assignments defined in the PHDLfile. The options are Try, Keep, and Ignore. The pinout retention capability of the fitter isvery high, so select Keep in the menu next to Pin preassignment. Click on the Compilebutton after setting the options to compile the design.Fit the DesignAfter compilation, you can fit the design into the target device by clicking the Fit button.During the fitting process, XPLA Designer generates three files that contain informationabout the design. The “tbird.fit” file contains the fitter report (Figure 13) which indicates24
