vhdl functions

Hello friends,

I am studying a program which uses the 2 functions viz - A_TOSTDLOGICVECTOR and A_WE_StdLogicVector. What are these functions and what is their usage. The code is size <= A_WE_StdLogicVector((((std_logic_vector'("0000000000000000000000000000000") & (A_TOSTDLOGICVECTOR(full_burst_on))) = std_logic_vector'("00000000000000000000000000000000"))), (std_logic_vector'("0") & (A_TOSTDLOGICVECTOR(std_logic'('1')))), LOCAL_BURST_LEN_s(1 DOWNTO 0));

Can you kindly point me to the relevant documents that explain these functions ?

Regards,

Vinod Karuvat.

    VHDL functions are either imported from a standard VHDL library or user defined, possibly in a different design entity, a package. The questioned function names seem to suggest user defined functions. So you have to search the respective design for their definition.
