Constructs in VHDL

Constructs in VHDL. Why HDLs?. In software everything is sequential Sequence of statements is significant, since they are executed in that order In hardware events are concurrent, so a software language cannot be used for describing and simulating hardware.

INTRODUCTION TO VERILOG HDL

INTRODUCTION TO VERILOG HDL. Presented by m.vinoth. What is verilog?. Verilog is a HDL- hardware description language to design the digital system. VHDL is other hardware description language. Virtually every chip (FPGA, ASIC, etc.) is designed in part using one of these two languages
