Synopsis

This manual offers an easy-to-read, easy-to-follow approach to digital fundamentals through the use of Complex Programmable Logic Devices (CPLDs). The use of advanced logic device technology prepares readers for using an industry-standard design environment. The first shorter section of the book contains a set of lab jobs using a single TTL chip: the 74LS00 quad 2-input NAND gate, allowing students to build a few simple circuits immediately. The second section contains a set of hands-on lab jobs with step-by-step instructions on using the Xilinx XC95108 CPLD. With its comprehensive appendices, this manual can prove useful to those who work with large-scale programmable devices such as CPLDs and FPGAs in the fields of electronics and engineering.

PREFACE

Up until now, almost all lab manuals for introductory digital courses at the Electronics Engineering Technology (EET) or Electronics and Computer Technology (ECT) level have been written around the use of TTL chips. One reason for not moving to CPLDs was the lack of a suitable target board at a reasonable price. But now several vendors are supplying such boards. The switches and LEDs of the target board are used to supply the input-output functions. Another reason, we believe, was the perception that a steep learning curve had to be climbed in order to use the software tools. The reality is that it's not as steep as it seems. This manual is an attempt to show the flatness of that curve by providing a set of hands-on lab jobs with step-by-step instructions on using the design software. The lab jobs are based on the Xilinx XC95108 CPLD and use the student version of the Xilinx® Foundation™ series software.

The manual is organized in two sections. The first, shorter section is a set of labs using TTL chips. This allows the students to build a few simple circuits immediately. Also, TTL is not totally gone; it is still used as "glue logic" in some applications. So it is still worthwhile for students to get their hands on the chips.

The second section, on using the CPLD, is the bulk of the manual. The first few labs in the CPLD section explore basic gates and Boolean algebra. We then move on to combinatorial circuits, including adders, multiplexers, encoders, and decoders. Next we explore latches and flip-flops, followed by counters and registers. Appendices include data for the XC95108 as well as documentation for two target boards. The appendices also include two tutorials and a glossary of terms for reference.

Selecting a target board is an important task for the instructor using this manual. The first decision is whether to build or buy. If the decision is to build, the board described in the appendix of Dave Van den Bout's book The Practical Xilinx® Designer Lab Book is a good example. If the decision is to buy, two possibilities are the XS95™ / XStend™ board combination from XESS® Corporation and the PLDT-1™ board from RSR® Electronics. The XESS board set is more advanced and supports mouse, VGA, and CODEC interfaces as well as switches, LEDs, and displays. It has an on-board 8051 microcontroller. The RSR board is a basic prototyping board with switches, LEDs, a 7-segment display, and connectors for ribbon cables. In writing this manual, we thought it would be useful to refer to a specific target board in order to avoid vagueness. So, many of the labs in this manual refer to the PLDT-1® board. However, the labs can be implemented on any target board using the same CPLD device.

Up until recently, almost all lab manuals for introductory digital courses at the Electronics Engineering Technology (EET) or Electronics and Computer Technology (ECT) level have been written around the use of TTL chips. But TTL is becoming hard to find since the industry has long since moved on to large-scale programmable devices such as CPLDs and FPGAs. Now several vendors are supplying CPLD-based experiment boards aimed at students. The switches and LEDs of the target board are used to supply the input-output functions.

Besides the problem of finding suitable lab boards, there is the perception that a steep learning curve has to be climbed in order to use the software tools required for programmable logic. The reality is that it's not as steep as it seems, as this manual attempts to show. We have written a set of hands-on lab jobs with step-by-step instructions on using the design software. The lab jobs are based on the Xilinx XC95108 CPLD, and use the student version of software supplied by Xilinx®.

The manual is in two sections. The first, shorter section is a set of lab jobs using a single TTL chip: the 74LSOO quad 2-input NAND gate. This allows the students to build a few simple circuits immediately. The TTL labs can be skipped if desired since the same concepts are covered in the CPLD labs. The second section, on using the CPLD, is the bulk of the manual. The first few labs in the CPLD section explore basic gates and Boolean algebra. We then move on to combinatorial circuits including adders, multiplexers, encoders, and decoders. Next we explore latches and flip-flops, followed by counters and registers. Appendices include data for the XC95108 as well as documentation for two target boards and a glossary of terms for future reference.

Selecting a target board is a key task for the instructor using this manual. The first decision is whether to build or buy. If the decision is to build, the board described in the appendix of Dave Van den Bout's The Practical Xilinx ® Designer Lab Book from Prentice Hall is a good example. If the decision is to buy, two possibilities are the XS95™ / XStend™ board combination from XESS® Corporation and the PLDT-3™ board from RSR® Electronics. The XESS board set is more advanced and supports mouse, VGA, and CODEC interfaces as well as switches, LEDs, and displays. It has an on-board 8051 microcontroller. In contrast, the RSR board is a basic prototyping board with switches, LEDs, 7-segment displays, and connectors for wiring. In writing this manual, we thought it would be useful to refer to a specific target board in order to avoid vagueness. Therefore many of the labs in this manual refer to the PLDT-3® board, but the labs can be implemented on any target board using the same CPLD device.

We were pleased by the many adoptions of the first edition. In this second edition, we have added a lab on a 256x8 RAM module. We have also spread out the TTL material over four labs instead of three.
