|/ | | | | | | | | | Eigen considers the EIGEN3_INCLUDE_DIRS and EIGEN3_DEFINITIONS variables to be deprecated and they will no longer be exported in the next release after 3.4.0: https://gitlab.com/libeigen/eigen/-/commit/f2984cd0778dd0a1d7e74216d826eaff2bc6bfab Use the IMPORTED target instead, which seems to be the preferred way of consuming third-party CMake libraries.

|\ | | | | ECP5: Add DSP signal remapping
| * Add remapping of DSP clk/ce/rst signals in a block.Adam Greig2023-01-044-0/+280
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each DSP block contains two slices, and each slice contains multiple MULT18X18D and ALU54B units. Each unit configures each register to use any of CLK0/1/2/3, CE0/1/2/3, and RST0/1/2/3 ports, and the ports are connected per unit (so for example, two MULTs in the same block could connect their CLK0s to different external signals). However, the hardware only has one actual port per block, so it's required that all CLK0 signals within a block are the same. Because the packer is in general allowed to combine two unrelated units into one block, it may end up combining units that use different signals for the same port, which would eventually have caused a router failure. This commit adds validity checks which ensure only unique signals are used per block, and adds remapping so that conflicting signals are automatically reassigned when possible and required.

|\ | | | | gowin: bugfix and improved clock router
| * gowin: improve clock wire routingYRabbit2022-12-305-45/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The dedicated router for clock wires now understands not only the IO pins but also the rPLL outputs as clock sources. This simple router sets an optimal route, so it is now the default router. It can be disabled with the --disable-globals command line flag if desired, but this is not recommended due to possible clock skew. Still for GW1N-4C there is no good router for clock wires as there external quartz resonator is connected via PLL. Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

|/ | | | | | | | | | When a single primitive occupies several cells, care must be taken when manipulating the parameters of that primitive: when creating cells, each cell must receive a copy of all the parameters and not modify them unnecessarily.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is a constraint conflict while placing IOs, the user gets an error message such as ERROR: Bel 'X0/Y27/io1' of type 'SB_IO' is not valid for cell 'my_pin' of type 'SB_IO' While this identifies the problematic cell, it does not explain why there is a problem. Add some verbose messages to allow users to determine where the problem is. This can result in something like Info: Net '$PACKER_VCC_NET' for cell 'my_pin' conflicts with net 'ce' for 'ce_pin' which provides something actionable.
