As an example, we look at ways of describing a four-bit register, shown in Figure 2-1. Using VHDL terminology, we call the module reg4 a design entity, and the inputs and outputs are ports. Figure 2-2 shows a VHDL description of the interface to this entity. This is an example of an entity declaration.

Modeling a RAM in VHDL (Two Write Ports) To model a RAM with two write ports in VHDL, use a shared variable instead of a signal. type ram_type is array (0 to 255) of std_logic_vector (15 downto 0); shared variable RAM : ram_type; XST rejects an attempt to use a signal to model a RAM with two write ports.

https://cse.usf.edu/~haozheng/teach/cda4253/doc/vhdl-stmt.pdf
A VHDL description has two domains: a sequential domain and a concurrent domain. The sequential domain is represented by a process or subprogram that contains sequential statements. These statements are exe-cuted in the order in which they appear within the process or subprogram, as in programming languages.

Delay Types. VHDL signal assignment statements prescribe an amount of time that must transpire before a signal assumes its new value. This prescribed delay can be in one of three forms: Transport: propagation delay only. Inertial: minimum input pulse width and propagation delay. Delta:

The extension of VHDL to support analog and mixed-signal systems began in 1989, as part of the second revision of IEEE Std 1076 targeted for a 1993 release. A large number of requirements to support analog and mixed-signal systems were submitted, and it soon became apparent that the complexity of the topic required

See Listing 1 and Listing 3 for more examples. Using parameter and the full_case directive in Verilog, we can specify arbitrary state encodings and still have efficient logic. In VHDL the state encodings are declared as an enumerated type (see Listing 5). The actual numeric value of the enumerated elements is predefined by the VHDL

[PDF File] VHDL & Verilog Compared & Contrasted
https://www.fpga4fun.com/files/vhdlvlogcompared.pdf
This is more a matter of coding style and experience than language feature. VHDL is a concise and verbose language; its roots are based on Ada. Verilog is more like C because it’s constructs are based approximately 50% on C and 50% on Ada. For this reason an existing C programmer may prefer Verilog over VHDL.

To illustrate, consider the declarations: type logic_level is (L, Z, H); type logic_array is array (integer range <>) of logic_level; function resolve_logic (drivers : in logic_array) return logic_level;
