In procedure was a bug regarding the test of the position of the
founded key/value pair. Because of this bug, a segmentation fault
happened when deallocationg the key/value pair. This is fixed now by
checking both neighbor entries for null
A new packae DictP.vhd is added which contains a simple implementation
of a dictionary type. It consists of a protected type t_dict which
contains procedures & functions which serve as methods to interact with
the protected type. The t_dict type is realised by a (double)
linked-list using access types.
The key type is string of arbitrary size, the data type is
std_logic_vector of arbitrary size. The t_dict type provides following
interface methods:
* set: set a key/value pair
* get: get a key/value pair
* del: remove a key/value pair
* init: initialise the dictionary
* clear: remove all key/value pairs
* hasKey: check if a key exists in the dictionary
* size: get number of key/value pairs
By using an actual version of GHDL, we don't need the VHDL-08
proposal libraries anymore. Enough features of VHDL-08 are integrated
in GHDL to compile OSVVM and our testbenches
The new common folder holds packages and designs, which can be used
either for synthesis & simulation. The first file is UtilP.vhd, a
package containing vatious helper functions:
* and_reduce(): function to and'ring all items of a vector, overloaded
for std_logic_vector & boolean_vector
* or_reduce(): function to or'ring all items of a vector, overloaded
for std_logic_vector & boolean_vector
* even_parity(): calculate the even parity of a std_logic_vector
* odd_parity(): calculate the odd parity of a std_logic_vector
By using an std_logic_vector access type for the data field in the
queue record, we cann now push data with any arbitrary length in the
t_queue object. Mixed lengths are also possible now :)
