gatemate: use CPE bridge (#1538)
* Add bridge support * Use bridge only if CPE is unused * do not use CPE_MULT for MUX routing * Fixed and documented * delay for CPE_BRIDGE * Convert bridge pips into bels Co-authored-by: Miodrag Milanovic <mmicko@gmail.com> * recursively reassign bridges * reconnect cell ports to new nets * handle inversion bits * sort data in output for easier compare * one to be removed after testing * debug message * Remove need for notifyPipChange * use same logic for detecting bridge pips * make sure that the pip used is the one assigned * one wire may feed multiple ports * remove #if * clean up wire binding * add debugging * fix * clangformat * put back to error * use tile instead of getting name out of bel/pip * bump chipdb * adressing review comments * Addressed last one --------- Co-authored-by: Lofty <dan.ravensloft@gmail.com> |

Gatemate FPGA initial support (#1473)
* Initial code for GateMate * Initial work on forming bitstream * Add CCF parsing * Use CCF to set IO location * Propagate errors * Restructure code * Add support for reading from config * Start adding infrastructure for reading bitstream * Fix script * GPIO initial work * Add IN1->RAM_O2 propagation * Fixed typo * Cleanup * More parameter checks * Add LVDS support * Cleanup * Keep just used connections for now * Naive lut tree CPE pack * Naive pack CC_DFF * pack DFF fixes * Handle MUX flags * Fix DFF pack * Prevent pass trough issues * Cleanup * Use device wrapper class * Update due to API changes * Use pin connection aliases * Start work on BUFG support * Fix CC_L2T5 pack * Add CPE input inverters * Constrain routes to have correct inversion state * Add clock inversion pip * Added MX2 and MX4 support * Fix script * BUFG support * debug print if route found with wrong polarity * Some CC_DFF improvements * Create reproducible chip database * Simplify inversion of special signals * Few more DFF features * Add forgotten virtual port renames * Handle muxes with constant inputs * Allow inversion for muxes * cleanup * DFF input can be constant * init DFF only when needed * cleanup * Add basic PLL support * Add some timings * Add USR_RSTN support * Display few more primitives * Use pass trough signals to validate architecture data * Use extra tile information from chip database * Updates needed for a build system changes * Implement SB_DRIVE support * Properly named configuration bits * autogenerated constids.inc * small fix * Initial code for CPE halfs * Some cleanup * make sure FFs are compatible * reverted due to db change * Merge DFF where applicable * memory allocation issue * fix * better MX2 * ram_i handling * Cleanup MX4 * Support latches * compare L_D flag as well * Move virtual pips * Naive addf pack * carry chains grouping * Keep chip database reproducible * split addf vectors * Block CPEs when GPIO is used * Prepare placement code * RAM_I/RAM_O rewrite * fix ram_i/o index * Display RAM and add new primitives * PLL wip code * CC_PLL_ADV packing * PLL handling cleanup * Add PLL comments * Keep only high fan-out BUFG * Add skeleton for tests * Utilize move_ram_o * GPIO wip * GPIO wip * PLL fixes * cleanup * FF_OBF support * Handle FF_IBF * Make SLEW FAST if not defined as in latest p_r * Make sure FF_OBF only driving GPIO * Moved pll calc into separate file * IDDR handling and started ODDR * Route DDR input for CC_ODDR * Notify error in case ODDR or IDDR are used but not with I/O pin * cleanup for CC_USR_RSTN * Extract proper RAM location for bitstream * Code cleanup * Allow auto place of pads * Use clock source flag * Configure GPIO clock signals * Handle conflicting clk * Use BUGF in proper order * Connected CLK, works without but good for debugging * CC_CFG_CTRL placement * Group RAM data 40 bytes per row * Write BRAM content * RAM wip * Use relative constraints from chipdb * fix broken build * Memory wip * Handle custom clock for memories * Support FIFO * optimize move_ram_io * Fix SR signal handling acorrding to findings * set placer beta * Pre place what we can * Revert "debug print if route found with wrong polarity" This reverts commit |
