UVM_RGM2.4 is the UVM version of the Cadence Register and Memory package that has been tested by multiple users on all major commercial simulators.

Library Enhancements:

• Created base class for virtual sequence having generic register access task
• Relaxed the rule, container interleaving now allowed to facilitate re-use
• Added support for backdoor HDL path for 'RTL' and other levels ('GATE')
• Bank memory (Parallel and Serial)
• Changed register backdoor write function to task
• Added static field in base reg class to allow backdoor force-delay programmable
• Function get_reg_file_by_name and get_addr_map_by_name support wildcard string search
• Function get_container_by_name added to rdb class, supports wildcard string search
• Added 'mask' field for register operation class
• Backdoor wr updates the register / memory which calls it
• Changed field access policy changed to string from enumerated type
• Field attributes can be over-ridden now
• Added call-backs for pre/post access for registers (uvm_rgm only)

 Parser :

•  Modified to generate fld access as string (for uvm_rgm_sfld_register's parameter)

Examples :

• Modified virtual sequence examples to use base parameterized virtual sequence
• Examples added for bank memory simple_examples/memory_bank
• Examples added on sequence reuse from block to system level: simple_example/seq_reuse/reuse1 and simple_example/seq_reuse/reuse2

Bug Fixed:

• Backdoor rd initializes the value from 'source', if present
• If mapped access is RO, update bytes should be skipped
• update_bv and compare_bv, when no_of_bytes are '0' should update and compare that leaf
• Built-in-seq : wr_rd seqence parameters getting over-ridden by get_config
• Memory : user_backdoor_[rd|wr] error with misalined incomplete burst
• Parser : Didn't handle field enumeration wth hex value
• Parser: RC and RCW produced the same code

Please look at the docs/release-notes.txt for more details.
