From a8a02f97a89597aac8310dd1adff6909e62cb7b4 Mon Sep 17 00:00:00 2001 From: Josh Blum Date: Thu, 19 Jul 2012 20:35:37 -0700 Subject: e100: tighten timing - less routing on EM_A There were a few places it was ok to use addr over EM_A. This makes routing sligtly easier for GPMC signals. --- usrp2/top/E1x0/core_compile | 2 +- usrp2/top/E1x0/timing.ucf | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'usrp2/top') diff --git a/usrp2/top/E1x0/core_compile b/usrp2/top/E1x0/core_compile index dd88094ff..ab992f29d 100755 --- a/usrp2/top/E1x0/core_compile +++ b/usrp2/top/E1x0/core_compile @@ -1,3 +1,3 @@ -iverilog -Wall -y. -y ../../control_lib/ -y ../../custom/ -y ../../fifo/ -y ../../gpmc/ -y ../../models/ -y ../../sdr_lib/ -y ../../coregen/ -y ../../vrt/ -y ../../opencores/i2c/rtl/verilog/ -y ../../opencores/spi/rtl/verilog/ -y ../../timing/ -y ../../opencores/8b10b/ -I ../../opencores/spi/rtl/verilog/ -I ../../opencores/i2c/rtl/verilog/ -y ../B100 -y $XILINX/verilog/src/unisims E100.v 2>&1 | grep -v timescale | grep -v coregen | grep -v models +iverilog -Wall -y. -y ../../control_lib/ -y ../../custom/ -y ../../fifo/ -y ../../gpmc/ -y ../../models/ -y ../../sdr_lib/ -y ../../coregen/ -y ../../vrt/ -y ../../opencores/i2c/rtl/verilog/ -y ../../opencores/spi/rtl/verilog/ -y ../../timing/ -y ../../opencores/8b10b/ -I ../../opencores/spi/rtl/verilog/ -I ../../opencores/i2c/rtl/verilog/ -y ../B100 -y $XILINX/verilog/src/unisims E1x0.v 2>&1 | grep -v timescale | grep -v coregen | grep -v models diff --git a/usrp2/top/E1x0/timing.ucf b/usrp2/top/E1x0/timing.ucf index 6bd559426..7d3d9e090 100644 --- a/usrp2/top/E1x0/timing.ucf +++ b/usrp2/top/E1x0/timing.ucf @@ -14,7 +14,7 @@ INST "EM_NCS6" TNM = gpmc_net; INST "EM_NWE" TNM = gpmc_net; INST "EM_NOE" TNM = gpmc_net; -TIMEGRP "gpmc_net" OFFSET = IN 7 ns VALID 14 ns BEFORE "EM_CLK" FALLING; +TIMEGRP "gpmc_net" OFFSET = IN 6 ns VALID 12 ns BEFORE "EM_CLK" FALLING; TIMEGRP "gpmc_net_out" OFFSET = OUT 14 ns AFTER "EM_CLK" RISING; //2 clock cyc per read #constrain interrupt lines -- cgit v1.2.3
