Most designers wish to utilize as much of a device as possible in order to enhance the overallproduct performance, or extend a feature set. As a design grows, inevitably it will exceed thearchitectural limitations of the device. Exactly why a design does not fit can sometimes bedifficult to determine. Programmable logic devices can be configured in almost an infinitenumber of ways. The same design may fit when you use certain implementation switches, andfail to fit when using other switches. This application note attempts to clarify the CPLD softwareimplementation (CPLDFit) options, as well as discuss implementation tips in CoolRunnerTM-IIdesigns in order to maximize CPLD utilization.

MP3 portable players are the trend in music-listening technology. These players do not includeany mechanical movements, thereby making them ideal for listening to music during any type ofactivity. MP3 is a digital compression technique based on MPEG Layer 3 which stores music ina lot less space than current CD technology. Software is readily available to create MP3 filesfrom an existing CD, and the user can then download these files into a portable MP3 player tobe enjoyed in almost any environment.

One of the most misunderstood constructs in the Verilog language is the nonblockingassignment. Even very experienced Verilog designers do not fully understand how nonblockingassignments are scheduled in an IEEE compliant Verilog simulator and do not understand whenand why nonblocking assignments should be used. This paper details how Verilog blocking andnonblocking assignments are scheduled, gives important coding guidelines to infer correctsynthesizable logic and details coding styles to avoid Verilog simulation race conditions

PCB methodologies originated in the United States.Units of measurement are therefore typically in Imperial units, not SI/metric units.

One of the strengths of Synplify is the Finite State Machine compiler. This is a powerfulfeature that not only has the ability to automatically detect state machines in the sourcecode, and implement them with either sequential, gray, or one-hot encoding. But alsoperform a reachability analysis to determine all the states that could possibly bereached, and optimize away all states and transition logic that can not be reached.Thus, producing a highly optimal final implementation of the state machine.

Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.
