CONV_STD_LOGIC_VECTOR( integer, bits ) CONV_STD_LOGIC_VECTOR( 7, 4 ). Converts an integer to a standard logic vector. Useful to enter constants.

In VHDL there is a difference between a single-bit vector and a scalar. In your case you are treating a std_logic_vector (0 downto 0) as if it were a std_logic. You cannot compare a std_logic_vector to a '1' or '0' value, however you can compare or assign one bit of the vector (even if it only has one bit) to '1' or '0' or you could compare or assign it to "1" or "0" which are single-bit vector values.

VHDL Syntax Reference (Author's Note: This document contains a reference on VHDL syntax that you may encounter during this course.It is by no means complete.There are many references available online that you may check for more complete material. 转换后的数据是原数据的二进制补码形式 VHDL中的数据转换函数conv_std_logic_vector的用法 std_logic_arith程序包里定义的数据转换函数：conv_std_logic_vector（A，位长）--INTEGER,SINGER,UNSIGNED转换成std_logic_vector。 These functions convert the arg argument to an integer. If the argument contains any undefined elements, a runtime warning is produced and 0 is returned.. The function provided by the std_logic_arith library can't convert a std_logic_vector to an integer because it is impossible to determine if it represents an unsigned or signed value.

When sending an integer as the argument to the CONV_STD_LOGIC_VECTOR function found in the STD_LOGIC_ARITH package, Express assumes that the resulting STD_LOGIC_VECTOR will always be a signed number. In the follow example, the number 20 will be converted to 010100, not just 10100, an
