Preface
Introduction
The Achronix Macro Cell Library provides the user with building blocks that may be
instantiated into the user’s design. These macros provide access to low‐level fabric primitives,
complex I/O block, and higher level design components. Each library element entry describes
the operation of the macro as well as any parameters that must be initialized. Verilog and
VHDL templates are also provided to aide in the implementation of the user’s design.
The Speedster Macro Cell Library is divided into nine separate chapters:
• Chapter 1 – “I/O Cells”
• Chapter 2 – “Registers”
• Chapter 3 – “Logic Functions”
• Chapter 4 – “Lookup Table (LUT) Functions”
• Chapter 5 – “Arithmetic Functions”
• Chapter 6 – “Memories”
• Chapter 7 – “Multipliers”
• Chapter 8 – “Special Functions”
• Chapter 9 – “PLL/DLL Clock Generators”
