axi_dacfifo: Fix constraints
2017-02-21 12:45:18 +00:00
set_property ASYNC_REG TRUE \
axi_dacfifo: Major update and redesign Redesign the axi_dacfifo, to increase the supported datarates. Major modifications: + The FIFO consist of two module: WRITE and READ. The axi_dacfifo_dac was deprecated. + Both the AXI write and AXI read transaction are controlled by two FSM, to increase redability of the code. + Support all the possible burst lengths [0..225], handles the last fractional burst on both sides correctly. + Common reset architecture throughout the design, all the internal registers and memories are reset on the posedge of dma_xfer_req + Delete all Altera related sources, for Altera projects avl_dacfifo should be used. WIP: foobar [WIP]axi_dacfifo: Update axi_dacfifo: Few minor updates, almost working state

axi_dacfifo: Update the constraints

axi_dacfifo: Rewrote constraints to be more specific Some of the wildcards matched too many paths and disabled the timing checks on intraclock paths.
