Hardware Description Languages

There are two popular hardware description languages (HDLs) to implement a digital system design on an FPGA. These are Verilog and VHDL. In literature, it is clearly emphasized that learning one HDL simplifies learning the other. Moreover, it is indicated that learning both HDLs is important to become an expert in this discipline. How-ever, most books on digital design pick either Verilog or VHDL alone and explain the concepts using it.
