inconsistent with 'net' object.

[santhosh]

hi i am new to UVM. In my design i have in-out port so interface i declared as wire.

while run the design by using make i got the one error :

** Error: (vsim-3044) ../uvc/i2c_slave_driver.sv(55): Usage of 'vif.sda' inconsistent with 'net' object.

here sda is in-out singal and vif is virtual interface of the design.

can any one help me to solve this problem..

Hi,

Try to declare the sda as wire and try. because of bi-directional we need to declare it as wire.

thanks,

mahee

Hi omahesh i already declares as wire in interface.. but when we have to drive the data to that port, this error is coming like 'vif.sda' inconsistent with 'net' object.(sda is port)

thank you for replay

Regard,

hi santhosh,

can you please put here your interface code?

Hi sagar this is my interface code of i2c

interface i2c_if (input wb_clk_i);

logic wb_rst_i; // synchronous active high reset

logic arst_i; // asynchronous reset

logic [2:0] wb_adr_i; // lower address bits

logic [7:0] wb_dat_i; // databus logic

logic [7:0] wb_dat_o; // databus output

logic wb_we_i; // write enable logic

logic wb_stb_i; // stobe/core select signal

logic wb_cyc_i; // valid bus cycle logic

logic wb_ack_o; // bus cycle acknowledge output

logic wb_inta_o; // interrupt request signal output

logic scl;

wire sda;

logic i2c_ack;

endinterface

Hi santhosh,

can you try with logic instead of wire for sda pin?
