Blocking and non-blocking are two types of assignments in Verilog that differ in their execution order and timing.
Blocking assignments execute in a sequential order and the next statement waits for the current statement to complete before executing.
Non-blocking assignments execute concurrently and the next statement does not wait for the current statement to complete before executing.
Blocking assignments are used for c...
Reset is a signal used to initialize the system or a specific module.
Reset is used to bring the system or module to a known state.
It is an asynchronous signal that overrides all other signals.
There are different types of resets such as power-on reset, soft reset, hard reset, etc.
Reset can be active high or active low depending on the design.
Reset can be generated internally or externally.
Reset can be used to clear regi
Task and function are both subprograms in Verilog/SystemVerilog, but task is used for procedural blocks and function is used for expressions.
Task is used for procedural blocks and can contain delays and event control statements.
Function is used for expressions and cannot contain delays or event control statements.
Functions can return a value, while tasks cannot.
Functions can be called from within tasks or other functio...
RAM and FIFO are essential components in FPGA design. Here's how to write code for them.
For RAM, define the memory size and data width, then instantiate the memory module and write/read data using the address bus and data bus.
For FIFO, define the depth and data width, then instantiate the FIFO module and write/read data using the write and read pointers.
Use synchronous or asynchronous reset signals to initialize the RA...

Compilation process in C involves preprocessing, compiling, assembling, and linking.
Preprocessing: Includes header files, macro expansions, and conditional compilation.
Compiling: Translates source code to assembly code specific to the target architecture.
Assembling: Converts assembly code to machine code in object files.
Linking: Combines object files and libraries to generate an executable file.
Function pointer syntax allows for storing the address of a function in a pointer variable.
Syntax: return_type (*pointer_name)(parameters)
Example: void (*funcPtr)(int) = &someFunction;
Reverse a given string
Use a loop to iterate through the characters of the string
Swap the characters from start to end of the string
Continue swapping until reaching the middle of the string
I applied via Company Website and was interviewed in Sep 2024. There was 1 interview round.
Memory allocation in C involves dynamically allocating and deallocating memory during program execution.
Memory allocation in C is done using functions like malloc, calloc, realloc, and free.
malloc function is used to allocate a block of memory of a specified size.
calloc function is used to allocate a block of memory for an array of elements, initializing all bytes to zero.
realloc function is used to resize a previously...

To start a sequence, you need to define the sequence type, specify the starting value, and set the increment or decrement value.
Define the sequence type: arithmetic, geometric, or custom
Specify the starting value of the sequence
Set the increment or decrement value for arithmetic or geometric sequences
For custom sequences, define the sequence pattern or rule
Examples: Arithmetic sequence starting from 1 with an increment...

DRAM is volatile memory that stores data temporarily, while SRAM is faster and more expensive but retains data as long as power is supplied.
DRAM stands for Dynamic Random Access Memory, while SRAM stands for Static Random Access Memory.
DRAM requires refreshing to retain data, while SRAM does not.
DRAM is slower and less expensive than SRAM.
Examples of DRAM include DDR3 and DDR4, while examples of SRAM include L1, L2, an

Packets are sent from source to destination through a series of network devices using routing protocols.
Packet is created at the source with source and destination IP addresses.
Packet is sent to the default gateway or router.
Router checks its routing table to determine the next hop for the packet.
Packet is forwarded to the next hop until it reaches the destination.
Destination receives the packet and sends an acknowledg
To delete a node from a single linked list, we need to find the node and update the pointers.
Traverse the list to find the node to be deleted
Update the previous node's pointer to point to the next node
Free the memory of the node to be deleted
Dynamic memory allocation in C allows allocation of memory at runtime.
Dynamic memory allocation is done using functions like malloc(), calloc(), realloc() and free().
malloc() allocates memory block of specified size and returns a pointer to the first byte of allocated memory.
calloc() allocates memory block of specified size and initializes all bits to zero.
realloc() changes the size of previously allocated memory block...
Interprocess communication is a mechanism that allows processes to communicate with each other in an OS.
IPC mechanisms include pipes, sockets, message queues, shared memory, and signals.
IPC can be used for synchronization, data sharing, and coordination between processes.
IPC can be implemented using system calls such as fork(), pipe(), socket(), and msgget().
