HCLTech Senior Hardware Design Engineer Interview Questions and Answers

The Spartan 6 FPGA block diagram consists of configurable logic blocks, memory blocks, I/O blocks, and clock management resources.

• Configurable Logic Blocks (CLBs) are the main building blocks of the FPGA, containing Look-Up Tables (LUTs) and flip-flops.

• Memory blocks provide storage elements for data.

• I/O blocks handle input and output signals.

• Clock management resources include Phase-Locked Loops (PLLs) and Delay-Locked ...read more

To convert 230V AC to 5V DC with 100% accuracy output, a step-down transformer, rectifier, and voltage regulator are needed.

• Use a step-down transformer to reduce the voltage from 230V AC to a lower level, such as 12V AC.

• Rectify the AC voltage using a bridge rectifier to convert it into pulsating DC.

• Filter the pulsating DC using capacitors to smooth out the waveform.

• Use a voltage regulator, such as a linear regulator or...read more
