This is just a simple logic optimization for an open drain output. If your code connects the T and I inputs together, i.e. pci_stop_t and pci_stop_i are driven by the same signal, or if the I will always be low when the T is low, then the logic would be equivalent.
--- Quote Start --- Hi, Altera also has IO buffers , these are called ALT_INBUF. Example : module io_primitives (data_in, data_out); input data_in; wire internal_sig; output data_out; alt_inbuf my_inbuf (.i(data_in), .o(internal_sig)); defparam my_inbuf.io_standard="1.8 V HSTL Class I"; assign data_out = !internal_sig; endmodule
Can any one exlpain the function of IBUF I was just curious since in my synchronous design where reset is also synchronous with clock the reset is applied to IBUF as I saw on View Technology Schematic in ISE. Also an ENABLE signal is connected to ibuff and both signals then routed to the whole circuit.

Im trying to migrate an Design from using Xilinx primitives to Intel Altera FPGA. The original design uses the IBUFDS for the clock signals. IBUFDS #(.DIFF_TERM("FALSE"), .IOSTANDARD("DEFAULT"), .
