As a newbie in fpga world i realized that it is possible to set pull updown resistors in verilog but i dont know how. It can be assigned by following way. A Typical Esd Protection Circuit I E Supply Clamp Learning Fpga And Verilog A Beginner S Guide Part 4 Altera Fpga I O Weak Pull Ups Electrical Engineering Stack I have written my code that works just fine but when i connect my xc3s400 to avr micro controller at the start up time it does weird things. Pull up resistor in verilog . Pull ups are often used with buttons and switches. I am experimenting with how the pullup and bufif0 switch level constructs work in verilog. The concept is to be used in an uvm based i2c top module for generating the sda and scl signals. Fpgas have limited bidirectional bus support. 2 if using verilog for your fpga design use the following. In other words a small a...
