- Summary

|
- V0.53 introduced a new C++ and Tcl based backend server, but only the

|
bindings.
|

- add 'asm-11', a simple, Macro-11 syntax subset combatible, assembler.
|
|
Can be used stand-alone to generate 'absolute loader' format files,
|
|
but also integrates tightly into the Tcl environment and is used as
|
|
building block in the creation of CPU test benches.
|
|
- use now doxygen 1.8.3.1, generate c++,tcl, and vhdl source docs
|
|
See section 9. in INSTALL.txt for details.

|
|
|
|
- Summary
|
|
- Introduce C++ and Tcl based backend server. A set of C++ classes provide
|
|
the basic rlink communication primitives. Additional glue classes provide
|
|
a Tcl binding. This first phase contains the basic functionality needed
|
|
to control simple test benches.
|
|
- add an 'rlink exerciser' (tst_rlink) and a top level design for a Nexys2
|
|
board (sys_tst_rlink_n2) and a test suite implemented in Tcl.
|
|
|
|
- Note: No functional changes in w11a core and I/O system at this point!
|
|
The w11a demonstrator systems are still operated with the old
|
|
backend code (pi_rri).

- Summary
|
|
- Introduce rbus protocol V3
|
|
- reorganize rbus and rlink modules, many renames
|
|
|
|
- New features
|
|
- vlib/rbus

|
|
- rbd_tester: test target, used for example in test benches
|
|
|

- Changes
|
|
- module renames:
|
|
- the rri (remote-register-interface) components were re-organized and
|
|
cleanly separated into rbus and rlink components:
|
|
rri/rb_sres_or_* -> rbus/rb_sres_or_*
|
|
rri/rri_core -> rlink/rlink_core
|
|
rri/rri_base_serport -> rlink/rlink_base_serport
|
|
rri/rrilib -> rbus/rblib
|
|
-> rlink/rlinklib
|
|
rri/rri_serport -> rlink/rlink_serport
|
|
rri/tb/rritb_sres_or_mon -> rbus/rb_sres_or_mon
|
|
- the rri test bench monitors were reorganized and renamed
|
|
rri/tb/rritb_cpmon -> rlink/rlink_mon
|
|
rri/tb/rritb_cpmon_sb -> rlink/rlink_mon_sb
|
|
rri/tb/rritb_rbmon -> rbus/rb_mon
|
|
rri/tb/rritb_rbmon_sb -> rbus/rb_mon_sb
|
|
- the rri low level test bench were also renamed
|
|
rri/tb/tb_rri -> rlink/tb/tb_rlink
|
|
rri/tb/tb_rri_core -> rlink/tb/tb_rlink_direct
|
|
rri/tb/tb_rri_serport -> rlink/tb/tb_rlink_serport
|
|
- the base modules for rlink+cext based test benches were renamed
|
|
rri/tb/rritb_core_cm -> rlink/tb/tbcore_rlink_dcm
|
|
rri/tb/rritb_core -> rlink/tb/tbcore_rlink
|
|
rri/tb/vhpi_rriext -> rlink/tb/rlink_cext_vhpi
|
|
rri/tb/cext_rriext.c -> rlink/tb/rlink_cext.c
|
|
|
|
- other rri/rbus related renames
|
|
bplib/s3board/s3_humanio_rri -> s3_humanio_rbus
|
|
w11a/pdp11_core_rri -> pdp11_core_rbus
|
|
|
|
- other renames
|
|
w11a/tb/tb_pdp11_core -> tb_pdp11core
|
|
|
|
- signal renames:
|
|
- rlink interface (defined in rlink/rlinklib.vhd):
|
|
- rename rlink port signals:
|
|
CP_* -> RL_*
|
|
- rename status bit names to better reflect their usage in v3:
|
|
ccrc -> cerr - indicates cmd crc error or other cmd level abort
|
|
dcrc -> derr - indicates data crc error or other data level abort
|
|
ioto -> rbnak - indicates rbus abort, either no ack or timeout
|
|
ioerr -> rberr - indicates that rbus err flag was set
|
|
|
|
- migrate to rbus protocol version 3
|
|
- in rb_mreq use now aval,re,we instead of req,we
|
|
- basic rbus transaction now takes 2 cycles, one for address select, one
|
|
for data exchange. Same concept and reasoning behind as in ibus V2.
|
|
|
|
- vlib/rlink/rlink_core
|
|
- cerr and derr state flags now set on command or data crc errors as well
|
|
as on eop/nak aborts when command or wblk data is received.
|
|
- has now 'monitor port', RL_MONI.
|
|
- RL_FLUSH port removed, the flush logic is now in rlink_serport
|
|
|
|
- restructured rlink modules
|
|
- rlink_core is the rlink protocol engine with a 9 bit wide interface
|
|
- rlink_rlb2rl (new) is an adapter to a byte wide interface
|
|
- rlink_base (new) combines rlink_core and rlink_rlb2rl
|
|
- rlink_serport (re-written) is an adapter to a serial interface
|
|
- rlink_base_serport (renamed) combines rlink_base and rlink_serport

|
|
- Summary
|
|
- Introduce ibus protocol V2
|
|
- Nexys2 systems use DCM
|
|
- sys_w11a_n2 now runs with 58 MHz
|
|
|
|
- New features
|
|
- ibus
|
|
- added ib_sres_or_mon to check for miss-behaving ibus devices
|
|
- added ib_sel to encapsulate address select logic
|
|
- nexys2 systems
|
|
- now DCM derived system clock supported
|
|
- sys_gen/w11a/nexys2
|
|
- sys_w11a_n2 now runs with 58 MHz clksys
|
|
|
|
- Changes
|
|
- module renames:
|
|
- in future 'box' is used for large autonomous blocks, therefore use
|
|
the term unit for purely sequential logic modules:
|
|
pdp11_abox -> pdp11_ounit
|
|
pdp11_dbox -> pdp11_aunit
|
|
pdp11_lbox -> pdp11_lunit
|
|
pdp11_mbox -> pdp11_munit
|
|
|
|
- signal renames:
|
|
- renamed RRI_LAM -> RB_LAM in all ibus devices
|
|
- renamed CLK -> I_CLK50 in all top level nexys2 and s3board designs
|
|
|
|
- migrate to ibus protocol version 2
|
|
- in ib_mreq use now aval,re,we,rmw instead of req,we,dip
|
|
- basic ibus transaction now takes 2 cycles, one for address select, one
|
|
for data exchange. This avoids too long logic paths in the ibus logic.
