A general introduction to terminology and history is followed by exposition of number systems and coding, combinatorial logic
, and synchronous sequential circuits.
ATF15xxBE CPLDs have a unique macrocell architecture with independent feedback paths for both the register and combinatorial logic
that fully exploits macrocell resources.
Also demonstrated are five user configurable flags per regulator channel, exponential decay filtering, and up to 32 digital 'trigger' outputs using single level combinatorial logic
, enabling the combination of internal states with 32 corresponding off-chip digital inputs to build complex system-level state signaling.
With automatic re-timing, the Synplify Pro software can now automatically reposition registers within combinatorial logic
to balance routing and ultimately improve circuit performance.
MDD replaces combinatorial logic
with lookup tables designated as multiple decision diagrams to improve simulation efficiency.
ClockIT propagates the actual tree and then does path and combinatorial logic
optimizations using the real skew and insertion delay.
These gates may be configured as combinatorial logic
and sequential elements (up to 18,000 flip-flops) or combined to form larger functions such as distributed memory and DSP (digital signal processing) cores.
With re-timing, registers are automatically moved within combinatorial logic
of the design to improve circuit performance.
Each MAX 3000A macrocell is individually configurable for either sequential or combinatorial logic
Typical applications for Nexar's initial release include 8-and 16-bit embedded systems for industrial controls, automotive and "white goods," and processor-based applications that currently use FPGAs to implement large blocks of combinatorial logic
Developed at Harvey Mudd College, this undergraduate textbook introduces combinatorial logic
and sequential logic circuit design, describes the computer's microarchitecture that connects hardware with software, and explains how to build a MIPS microprocessor.

, simplified conditional and case statements, extended assignments, new and enhanced operators, extended bit string literals, enhanced port maps, context declarations and clauses.
