This article introduces the usage of DSP48E2 instantiation, as follows: DSP48E2 #( // Feature Control Attributes: Data Path Selection .AMULTSEL("A"), // Selects A input to multiplier (A, AD) .A_INPUT("DIRECT"), // Selects A input source, "DIRECT" (A port) or "CASCADE" (ACIN port) .BMULTSEL("B"), // Selects B input to multiplier (AD, B) .B_INPUT("DIRECT"), // Selects B input … Read more
Hardware Description Language (HDL) is the cornerstone of modern digital system design, used as the core tool to describe hardware behavior and structure in both Field Programmable Gate Arrays (FPGA) and Application-Specific Integrated Circuits (ASIC). However, the fundamental differences in implementation, design processes, and target applications between FPGA and ASIC lead to significant differences in … Read more
Concept of Logic Analysis The logic analyzer is also a very commonly used instrument, just like the oscilloscope, and is one of the classic instruments for digital design and measurement. When measuring digital circuits, when should an oscilloscope be used? Generally, an oscilloscope can be used when precise parameter information (such as time intervals and … Read more
