Hi everyone,

I’m working with **SPI BFM** on **GHDL** and I had a run time error with the UVVM\_SUPLEMETARY sample code (spi\_vvc\_tb.vhd):

UVVM-master/bitvis\_vip\_scoreboard/src/generic\_sb\_pkg.vhd:546:14:error: type of variable “vr\_sb\_queue” referenced before its elaboration  
variable vr\_sb\_queue : sb\_queue\_pkg.t\_generic\_queue;

**Compilation in GHDL:**

ghdl -a --work=bitvis\_vip\_spi --std=08 -frelaxed -fsynopsys spi\_common\_pkg.vhd  
ghdl -a --work=bitvis\_vip\_spi --std=08 -frelaxed -fsynopsys spi\_master.vhd  
ghdl -a --work=bitvis\_vip\_spi --std=08 -frelaxed -fsynopsys spi\_slave.vhd  
ghdl -a --work=bitvis\_vip\_spi --std=08 -frelaxed -fsynopsys spi\_pif.vhd  
ghdl -a --work=bitvis\_vip\_spi --std=08 -frelaxed -fsynopsys spi\_vvc\_tb.vhd  
ghdl -e --work=bitvis\_vip\_spi --std=08 -frelaxed -fsynopsys spi\_vvc\_tb  
ghdl -r --work=bitvis\_vip\_spi --std=08 -frelaxed -fsynopsys spi\_vvc\_tb --vcd=GTK\_spi\_vvc\_tb.vcd

It seems that the error comes from line 126 of the vvc\_methods\_pkg.vhd file.

Best regard,  
Thanks.

Oscar.

Hi,  
We have made a fix that will be released soon.  
You can move the declaration of the scoreboard package from vvc\_methods\_pkg.vhd to transaction\_pkg.vhd and you should be able to run.

I’ve got the same bug on Ethernet examples from bitvis\_vip\_ethernet, I suppose the same solution can be applied do you ??

Hi,  
Yes, I belive you will have to make the same changes.
