From 972e652dc8754e7c0dc92fd62b8a5575ee8290c6 Mon Sep 17 00:00:00 2001 From: David Brouwer <dbrouwer@astron.nl> Date: Thu, 2 Nov 2023 11:40:00 +0100 Subject: [PATCH] Copied the ip_arria10_e2sg/ram/ip_arria10_e2sg_<ram_name>.vhd file and copied in the component declaration and instance example from generated/ram_2port_2040/sim/ip_agi027_xxxx_ram_<ram_name>_ram_2port_2040_<generated_hash>.vhd. Updated information header. Changed the technology_name from ip_arria10_e2sg to ip_agi027_xxxx. Checked the differences between the underlying files where the original vhd file is based on. There are no significant differences. Most of the parameters that are different are added and commented out. --- .../ram/ip_agi027_xxxx_ram_r_w.vhd | 160 ++++++++++++++++++ 1 file changed, 160 insertions(+) create mode 100644 libraries/technology/ip_agi027_xxxx/ram/ip_agi027_xxxx_ram_r_w.vhd diff --git a/libraries/technology/ip_agi027_xxxx/ram/ip_agi027_xxxx_ram_r_w.vhd b/libraries/technology/ip_agi027_xxxx/ram/ip_agi027_xxxx_ram_r_w.vhd new file mode 100644 index 0000000000..9bc409b8f4 --- /dev/null +++ b/libraries/technology/ip_agi027_xxxx/ram/ip_agi027_xxxx_ram_r_w.vhd @@ -0,0 +1,160 @@ +-- ----------------------------------------------------------------------------- +-- +-- Copyright 2023 +-- ASTRON (Netherlands Institute for Radio Astronomy) <http://www.astron.nl/> +-- P.O.Box 2, 7990 AA Dwingeloo, The Netherlands +-- +-- Licensed under the Apache License, Version 2.0 (the "License"); +-- you may not use this file except in compliance with the License. +-- You may obtain a copy of the License at +-- +-- http://www.apache.org/licenses/LICENSE-2.0 +-- +-- Unless required by applicable law or agreed to in writing, software +-- distributed under the License is distributed on an "AS IS" BASIS, +-- WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +-- See the License for the specific language governing permissions and +-- limitations under the License. +-- +-- ----------------------------------------------------------------------------- +-- +-- Author: D.
