Fpga Engineer Interview Questions

681 fpga engineer interview questions shared by candidates

Mostly asked basic digital design questions. Draw a sequential circuit, what is the makeup of an FPGA (LE, Registers etc), Draw a mod 10 counter, draw the schematic for a half adder. Once i drew the schematic for it i was then ask to draw it as if i had only NAND gates.

1) Code an accelerator block in HLS according to a given specification, complete with Linux drivers and a user space programming interface. Discuss design choices, approach and tradeoffs. 2) Write RTL for a module counting the drift of a fast clock signal in relation to a high precision 1PPS-signal.

question were quite simple in first interview .. very things basics ..he didn't go much into deep ..in the second interview c-programming pointers , void statement and diff b/w static memory location and dynamic memory location matlab- diff script file and function file.. call by reference ,pass by reference.. a.b and a*b verilog initial statement and fork and join , fpga chipscope,pci interface ,,simulators modelsim ..nc verilog,
