R. Timothy Edwards ab85f607e9
Corrected the definitions for the pullup and pulldown input modes (#51) 
in "defs.h" per the github issue #15 posted by Sylvain Munaut.

Tim Edwards 7a45a096a5 Added a testbench that exercises the SRAM 2nd (read-only) port, as 
it was configured for the caravel_pico SoC, with the housekeeping
SPI able to access the upper 256-word section of the memory if the
CSB bit in the housekeeping control register is cleared.  This
testbench tests both access through housekeeping and access directly
from the SoC through the memory-mapped address.

Tim Edwards 1526214cc1 Modifications to some of the Makefiles to make the specific RISC-V 
architecture type passed to gcc as the value to the '-march='
option an environment variable, setting that environment variable
to "rv32imc" by default, and overriding it with "rv32ic" specifically
for the new caravel_pico without the multiplier and divider option,
on testbenches "mem" and "storage" which both have multiplies in the
C code.

jeffdi d4e6ed5684 adding user_project_wrapper empty files -- gds & lef 2021-12-16 12:29:35 -08:00
Tim Edwards d4b4b7abb8 Fixed one bad error in clock_div which had been done without my 
knowledge and which went undetected since before MPW-one.  Modified
the "pll" and "sysctrl" testbenches so that they run and measure
something useful.  Both exercise the clock monitoring on GPIO
outputs functions.  The PLL test also runs the digital locked
loop (behavioral verilog).  The PLL test overlaps sysctrl, but
"pll" cannot be run on gate level verilog, whereas "sysctrl" can.
 2021-12-06 21:37:51 -05:00
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.
 2021-12-06 19:38:24 -05:00
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).

manarabdelaty 856539ca59 Update storage testbench to work with one 2K block 2021-11-12 17:14:21 +02:00
Tim Edwards e09640425a Added the user-power-down version of hkspi (hkspi_power) to the list 
of patterns to run in the Makefile for verilog dv, since that pattern
has been debugged and now runs correctly.
 2021-11-03 11:33:13 -04:00
Tim Edwards 1d359690ac Added testbench for checking that the housekeeping SPI is accessible when 
the user area is powered down.  Because this requires some changes to the
padframe definition, this testbench currently fails.
 2021-11-02 21:58:47 -04:00
Tim Edwards a2aacdb5d2 Removed some commented-out test code from sram_exec.c to make the 
code clearer and less cluttered.
 2021-10-31 17:06:05 -04:00
Tim Edwards a360b77618 Added a testbench that demonstrates copying a portion of a program in 
flash into SRAM and executing it.
 2021-10-31 16:58:44 -04:00
Tim Edwards 00e0a5f603 Corrected the two failing testbenches (which needed fixing because 
the implementation of the housekeeping module changed the addresses
of the signals being exercised).
