Logical Devices, Inc. provides this manual “as is” without warranty of any kind, either should not be viewed as any sort of definitive reference on the CUPL. WinCUPL is a language designed to support the development of PLDs .. into a document such as a manual and file for input into the CUPL simulator. 2.

Don t-care values are supported for the input decode value, but not for the output decoded value. Under the file menu click on open. This might also be called low-true. This will reduce the number of different devices in stock and increase the quantity purchased. Arithmetic operations can be performed in the repeat body. This feature is manuxl on the Atmel ATF family of devices. In any PLD design, the designer is primarily concerned with whether a signal is true or false.

As the name suggests, these devices can only be programmed once. Examples of some valid variable names are: The manaul body can be any CUPL statement. These keywords cannot be used as names in CUPL.


The CUPL Environment

This options causes the compiler to configure the macrocells in the Atmel PLD device to D-type registers. After pin declarations are made, remove any lines. AP extension is used to set the Asynchronous Preset of a register to an expression.

The original document is copyrighted by Logical Woncupl, Inc. However, this method requires the use one of the devices output or buried registers. CUPL uses these extensions to configure the macrocells within a device. The equation for the 3-input XOR gate is derived as follows The equation for the 3-input XOR gate is derived as follows The last four product terms in the above derivation are the four 1-minterms in the 3-input XOR truth table.

The following table shows the arithmetic function and its bases.

With the virtual device, the equation itself must be inverted, since the compiler ignores the polarity in the pin declaration.

The result of an operation between two sets is a new set in which the operation is performed between elements of each set.

This is used in devices that have one or more product terms connected to the Asynchronous reset of the register. Lecture-2 Programming Fundamental Instructor Name: To familiarize with combinational and sequential logic circuits Combinational circuits More information. This means that the circuits have a memory. What Is a State Machine? Please reference these manusl numbers for pinnode declarations. The format is as follows: As with node declarations, most internal nodes are active-level HI; therefore, the exclamation point should fe be used to define the polarity of an internal signal as active level LO.
