- Vivado is used with -fsm_extraction one_hot. Starting with Vivado 2016.3
this triggers fsm recognition and re-coding of two gray counter modules.
This not only defeats the purpose of the gray coded counter, it also
caused some constraints to fail. Added attributes to prevent fsm extraction
- the logic of `connect_hw_server` and `get_hw_servers` changed after Vivado
2015.1. The `make <design>.vconfig` command worked up to Vivado 2016.2 due
to some recovery mechanism, and finally broke with 2016.3. Fixed the
call to `get_hw_servers`.
- tools/tcl/rw11/shell.tcl
- rename all command, add leading '.' to guarantee uniqueness
- add .csus,.csto,.cres,.csta: suspend, stop, reset and start CPU
- add .cme,.cmd,.cml: enable, disable and list cpu monitor (dmcmon)
- add .ime,.imd,.imf,iml: enable, diable, setup filter and list ibus monitor
- add ?m,?u: show mmu and ubmap status
- add .hr: help on registers
- improve buildin help, better .h and additional .ha (for aspec's)
- redo ^D,.q..qq logic (assuming that it's default shell in ti_w11)
- tools/tcl
- ibd_ibmon/util.tcl: add proc filter
- rw11/dmcmon.tcl: cm_print: protect against empty lists
- pdp11_sequencer.vhd: CPUERR cleared by CRESET
- mminki.mac: added, procedure to initialize MMU, kernel I space only
- test_w11a_cpuerr.tcl: added, test cpuerr register
- added more README's
- editorial changes
- xsim support complete (but many issues to be resolved yet)
- Added configurable w11a cache
- Removed some never documented and now strategically obsolete designs
rbus->ibus window. Replaces with a 4k word window for whole IO page.
- utilize rlink protocol version 4 features in w11a backend
- use attn notifies to dispatch attn handlers
- use larger blocks (7*512 rather 1*512 bytes) for rdma transfers
- use labo and merge csr updates with last block transfer
- this combined reduces the number of round trips by a factor 2 to 3,
and in some cases the throughput accordingly.
- Goals for rlink v4
- 16 bit addresses (instead of 8 bit)
- more robust encoding, support for error recovery at transport level
- add features to reduce round trips
- improved attention handling
- new 'list abort' command
- For further details see README_Rlink_V4.txt
- use own C++ based tcl shell tclshcpp instead of tclsh
divisor or quotient were the largest negative integer (100000 or -32768).
This is corrected now, for details see ECO-026-div.txt
- some minor updates and fixes to support scripts
- xtwi usage and XTWI_PATH setup explained in INSTALL.txt
- after 0.581: documentation updates, no functional changes
- from 0.5 -> 0.6:
- revised ibus and rbus protocol; backend server rewritten; Nexys3 port;
Cypress Fx2 support; LP11,PC11 support
- new reference system
- switched from ISE 13.3 to 14.7.
- map/par behaviour changed, unfortunately unfavorably for w11a.
On Nexys3 no timing closure anymore for 80 MHz, only 72 MHz can
be achieved now.
- new man pages (in doc/man/man1/)
- support for Spartan-6 CMTs in PLL and DCM mode
- C++ and Tcl based backend server now fully functional, supports with
DL11, RK11, LP11 and PC11 all devices available in w11a designs
- the old perl based backend server (pi_rri) is obsolete and removed
- operating system kits reorganized
