Unable to use axi_write in my project

VVC Bitvis VIP AXI
1

Hi everyone! I’m new of UVVM and this is my first experience of verification design; anyway…

I must test (with UVVM framework) one IP. This IP has a simle AXI memory mapped interface (ADDR, DATA, READY, VALID, LEN and STROBE signal). In these days i’m playing with axi BFM interface.

Now my problem. When I try to use axi_write

axi_write(x"0000ffff",x"01",“test”,clk_stimuli,axi_mm_if);

obtain the following error in compile time:

** Error: C:\Users\Enrico\Desktop\smart-dma\tb.vhd(186): (vcom-1600) No feasible entries for subprogram "axi_write".

It looks like a casting\overloading problem but I don’t understand where is the problem :-/

I use modelsim 10.6d

Hi,

It seems like you are missing some parameters in the axi_write() call. You can check the documentation in bitvis_vip_axi/doc/axi_bfm_QuickRef.pdf for more information on the parameters.

Hi! Thank you for your reply… At the end I decide to build my “axi” BFM from scratch because the bitvis axi implementation it’s overkilled for my purpose.

I spent about 2-3 working days for coding my BFM (my FIRST BFM)… UVVM looks awesome :smile:
