Sorry, but computer says no. The modified vhdl-compiler-alist value does not match its declared type.

You can easily check this by running `M-x customize-variable vhdl-compiler-alist`; it will show the contents as a single big text field and say (mismatch).
If the value matches the type, it would have shown the value structurally.

Another check is to run `make -C test test-custom-opts`, which checks the values of all defcustom variables in Emacs.

In this case it seems to be the `(2 . 3)` values at the end of the error message sublists. Remove them and the value matches the type.
If those (2 . 3) are important, perhaps you want to change the type instead but you would have to maintain compatibility somehow. I see there is a lot of code dealing with changes to the type of that variable in vhdl-mode.el.
