Section 3.4.1 describes some of the commands such as Query, Ack, Req_rn, and Write. The
corresponding macros representation is shown in Figure 3.22. Figures 3.23 through 3.25
show the synthesis process of the Query primitive.

3.4.4.3.1 Custom Hardware-Based Tag
Using the RFID compiler, up to ?¬?ve inventory commands of the ISO 18000 Part 6C
standard were implemented with 0.16 mm custom cell-based ASIC hardware and a Spartan
3 FPGA. To evaluate the effectiveness of the automated approach in providing a rapid
prototype and accurate estimate of resource requirements of the RFID system, the areas of
the automated tag designs generated by the RFID Compiler have been compared with the
areas of our own manual tag designs for the above targets. The tools used for estimating
area are design compiler and precision synthesis.
Table 3.4 shows the total area of ISO 18000 Part 6C tag designs for a 0.16 mm ASIC. Table
3.5 shows the resource utilization of Gen-2 tag designs for a Spartan 3 FPGA. The FPGA
resource utilization is almost the same for all the designs and actually decreases slightly
with the automated approach. For the ASIC implementation of ?¬?ve primitives, there is a
nominal increase in area of up to 10.
