determine whether or not the design looks reasonable For most reasonable size designs, however, it can be very difficult to determine how well the synthesizer implemented the function The designer looks at the report files to determine the quality of the synthesis output The most common output files are the timing report and the area report Most synthesis tools produce a number of other reports such as hierarchy reports, instance reports, net reports, power reports, and others The most useful reports initially are the timing and area reports, because these are usually the most critical factors Following is a sample area report:

The area report tells the designer the size of the implemented design The units of measure are determined by the units used when the synthesis library was implemented For instance, the typical unit for ASIC designs is equivalent 2-input NAND gates, or gate equivalents Using this measurement, a 2-input NAND gate would consume one gate equivalent, a 2-input AND gate would also consume one gate equivalent A 4-input NAND gate would consume two gate equivalents For FPGA designs, equivalent gate measurements vary from manufacturer to manufacturer

because each has a different-sized basic cell In the preceding sample area report, the design produced 8 LC (Logic Cells) and 7 Carry devices A typical LC is 10 to 12 logic gates; the Carry device is 2 to 3 gates So, this example would represent about 90 to 120 gates The area report shows the designer how much of the resources of the chip the design has consumed The designer can tell if the design is too big for a particular chip and the designer needs to target a larger chip, if the design should go into a smaller chip, or if the current chip will work fine The designer can also get a relative size of the design to use in later stages of the design process The timing report shows the timing of critical paths or specified paths of the design The designer examines the timing of the critical paths closely because these paths ultimately determine how fast the design can run If the longest path is a timing critical part of the design and is not meeting the speed requirements of the designer, then the designer may have to modify the VHDL code or try new timing constraints to make the path meet timing The following is a sample timing report:

In this report, the worst-case path is listed shown with estimated time values for each node traversed in the design The timing analyzer calculates the time for a path from an input pin to a flip-flop or output, or from a flip-flop output to a flip-flop input, or output pin The designer has the ability to ask for the timing for particular paths of interest, or of the paths that have the longest timing value, and how many to display As mentioned previously, the worst-case paths ultimately determine the speed of the design For instance, in this case, the worstcase path is 138 nanoseconds; therefore, the fastest this design would be able to run is about 72 MHz The last type of output data that the designer can examine is the netlist for the design in the target technology This output is a gate or macro-level output in a format compatible with the place and route tools that are used to implement the design in the target chip For instance, most place and route tools for FPGA technologies take in an EDIF netlist as an input format The primitives used in the netlist are those used in the synthesis library to describe the technology The place and route tools understand what to do with these primitives in terms of how to place a primitive and how to route wires to them The following example uses a VHDL netlist for ease of understanding To save space (and boredom), this is not a complete netlist, but gives the reader an idea of how a netlist is structured The complete netlist can be found on the included CD:
