Tim Edwards a9bb8bcd0a A handful of changes/corrections: (1) Housekeeping signal "user_clock"
(input for monitoring) changed from being connected directly to the
user project (where it shouldn't be) to the same signal on the input
side of the management protect block (where it should be).  This is
functionally the same.  Checked for any other signals connected
directly from the user project to any block other than mgmt_protect,
didn't find any (good).  Modified the gate-level netlists and top-level
layouts for caravel and caravan with the corresponding change.  This
was the only change affecting layout.  Also:  Revised the "pll"
testbench.  This is still ongoing work.  Also:  Fixed the way the
pins on I/O pads are declared in chip_io.v, mprj_io.v, and pads.v, so
that it isn't so bizarre.  Most of this change is functionally
agnostic (just a change in the way the ifdefs work), but did fix an
incorrect ifdef that causes the whole user power domain to be broken.

Tim Edwards 3246e64407 Correction to the gen_gpio_defaults.py file, which was accidentally
overwriting the top-level gate-level verilog netlist with the
modified layout file contents.

Tim Edwards 9da6bab4a8 Corrected DRC errors on the non-Manhattan edges of the caravel
and open source logos.  Modified the gpio_defaults_block layout
so that open holes are not created in the metal1 when the vias
are moved by the defaults block configuration script.

Tim Edwards bd6af6dddc Modified all of the Makefiles to better handle the GL netlist simulations,
which is now done through setting an environment variable to point to the
location of the management SoC wrapper.  Added the missing user project
wrappers to the GL directory (copied from the original caravel repository),
and also the GL version of chip_io_alt.  Modified the caravan_netlists and
caravel_netlists files to import the correct list of gate level netlists,
which has been reduced by moving "include" statements for components of the
management SoC into the management SoC repository (e.g., caravel_pico).

Tim Edwards b23ec956f3 Corrected the mprj_bitbang testbench verilog (it had not been corrected for
the change in the implementation of the serial loader, which split the load
signal out as a separate bit, and therefore had a separate bit-bang entry).

Tim Edwards 2691903104 Reworked part of the layouts of both caravel and caravan to move
the clocking subcircuit from inside the pad area near the "clock"
pin to under the DLL.  This prevents the DLL from having its
outputs travel all the way across the chip to reach the clocking
cell and then have the multiplexed clock travel all the way back,
especially as the DLL outputs are high-speed signals (up to 150
MHz).

Tim Edwards 024801ab56 Extended the gen_gpio_defaults.py script to handle modifying the
verilog gate-level netlists to match the correct GPIO default
value assignments, and modify the top level gate-level caravel.v
and caravan.v netlists to match.

Tim Edwards 4cf7aa2983 Changed the synchronized reset to occur on the clock falling edge
to give more timing margin when reset is released (note to self:
shouldn't the ext_reset also be synchronized?).

Tim Edwards 6482c1e011 Corrected the set_user_id.py script to (1) reverse the position of
characters in the user_id_textblock layout, which was backwards,
and (2) add a path reference to "hexdigits" for each new character
layout encountered in the file, so that the text block layouts
are found even if "addpath hexdigits" has not been specified.
There were some other corrections to handling gzipped files that
probably does not apply in practice, where "make uncompress" has
been run prior to the set_user_id.py script.

Tim Edwards 0f90c813ed Added a missing route that was not completed in the previous layout
update.  Also changed the defaults block types in the layout so that
they match the gate-level netlist.  This does not change the behavior
after assembly but lets LVS run correctly on the layout prior to final
assembly.

Tim Edwards e0a318d2bf Fixed the GL verilog for caravel and caravan to add the two changes
just made to the RTL verilog and layout, to separate out hk_cyc_o
and to hook up the housekeeping user_clock input.
2021-11-30 12:31:07 -05:00
Tim Edwards 1035e8b469 Updated caravel and caravan layouts to reflect the simple change
to housekeeping and the management core wrapper to separate the
wb_cyc_i signal and connect to new signal hk_cyc_o on the
management core.  Also:  Fixed a dangling input (user_clock) on
the housekeeping (minor error caused by the earlier refactoring
and unnoticed because there is no testbench covering that
function).

manarabdelaty c4efcec989 [DATA] Update housekeeping views 2021-11-30 13:00:33 +02:00
Tim Edwards 4c0a2303b1 Modified the GL netlists to match the layout for the GPIO defaults
blocks;  that is, there are special versions of the block for the
first 6 GPIO pins.  That should allow the GL netlists to simulate,
although the end goal is to have the gen_gpio_defaults.py script
modify the GL netlists to exactly match the configuration, as is
done for the .mag layouts.
2021-11-29 20:17:11 -05:00
Tim Edwards 84c97b74b2 Corrected the instance names in the layout so that they once again
correspond to what the script gen_gpio_defaults.py is looking for.

Tim Edwards cd4a052344 Made the same change to caravan as was made to caravel in the
last commit.
2021-11-29 14:27:02 -05:00
Tim Edwards 4dac106297 This (late and invasive) change modifies the housekeeping block to
add a separate signal for the houskeeping wb_cyc_i wishbone signal,
instead of combining it with the user project's wb_cyc_i.  This
change makes it compatible with the LiteX implementation of the
wishbone bus.
