about PLL and buffer ram in camera_vga_display_top module #1

Hello, I am a freshman at Bilkent University, and I'll use your code for my Digital Design courses' term project. I first converted all codes into VHDL, yet I had an issue. You declared clock_PLL_100_50_25MHz_inst and buffer_RAM_12x131072_inst in the camera_vga_display_top module, yet you haven't included their codes. I've searched for their code online but couldn't find anything useful. Can you please assist me with these? Regards

The corresponding code part can be found in the following:

clock_PLL_100_50_25MHz_inst : entity work.clock_PLL_100_50_25MHz
        port map (
            clk_out1 => clk_100mhz,
            clk_out2 => clk_50mhz,
            clk_out3 => clk_25mhz,  
            resetn => reset, -- assuming resetn is the same as reset
            locked => locked,
            clk_in1 => clk
        );

buffer_RAM_12x131072_inst : entity work.buffer_RAM_12x131072
        port map (
            clka => clk_50mhz,
            wea => wea,
            addra => save_address,
            dina => RGB_444_data,
            clkb => clk_50mhz,
            addrb => read_address,
            doutb => doutb
        );
